Frequenty asked questions​
​
Q: Is your storage a high pressure cylinder?
A: Actually no - our storages are charged at pressures 10-35 bar, but they are operating at pressures below 10 bar. However the bodies of our tanks can stand pressure over 100 bar.
Q:Is your tank a gas storage?
A: No, in our storage hydrogen is stored in the form of solid metallic hydride.
Q:How do I know when I used up hydrogen and need to recharge it?
A: If the pressure in the storage dropped below 1.5 bar (at room temperature) you need to recharge it.
Q: Shall I add pressure gauge on your storage?
A: No, except you need to record pressure in your experiments.
​Q:Can your storage store other gases?
A:No, our cylinder is storing only hydrogen.
​
Q:What will happen if your storage is charged with other gases?
A:It will work just as a high pressure tank. However, if the stored gas (CO, oxygen, etc.) can react with the storage alloy, the storage will lose its original function.
Q:Is a regulator required while using H Bank hydrogen storage system?
A:Since the pressure in our storage remains almost constant until 95% of the gas is used, no regulator is needed.
Q:How long does it take to charge the H Bank System?
A:Recharging is simple and fast for our systems. For example, it only takes about 30 minutes to charge a 50 liters canister at ambient air or just 10-15 minutes if room temperature water bath is used.
Q:How long is the lifespan of the H Bank system?
A:If charged with 99.99% or higher purity hydrogen, the charge/discharge recycling life of our system can be over 3000 cycles with less than 10% decay in storage capacity. In fact, if you recharge our storage every day you can use it for more than 8 years.​
The bodies of our tank canisters are made from high-grade low carbon SS361L stainless steel or SS321 stainless steel, which ensures the system’s necessary strength as well as prevents it from oxidation related negative effects.
System’s complete stainless steel construction allows increasing designed maximum gas flow rate while using hot water bath.

Gas Charging Procedures
1.To connect the system to high-pressure (14.5MPa) hydrogen source, hydrogen pressure reducer and metallic pipelines (stainless steel or copper) must be used.
2.Purge the connection pipelines with light gas flow from the high-pressure tank before connecting it to the storage system. Use the pressure reducer to adjust the pressure in the feeding pipeline up to 3.5 MPa.
3.Turn on the system valve to begin the charging process. Due to the lower canister temperature, the rate of charging is higher in the beginning of the process, but it will slow down after.
​
4.The system is fully charged, if the pressure (3.5 MPa) remains unchanged within ~ 1-2 minutes, while the pressure reducer on the high-pressure tank is turned off. If the pressure decreased, it means that the system is not full charged and the charging procedure must be continued.
5.If the charge process is over, turn off the system valve and remove the connecting hose.
6.
To reduce the charging time cold-water bath can be used. However, it is important to avoid between the main valve and the connector with water.
7.
For systems with operating pressure higher than 0.7MPa, water bath with temperature below 10°C is recommended. Similarly, it is important to avoid any form of contact between the valve and connector with water.
Process can be reversed if the hydrogen pressure is lowered below some certain value.
The gas desorption process will be accompanied with heat absorption from environment.
※ Important after-charging procedure ※
After the charging process is finished and the storage is disconnected from the high pressure hydrogen source, the pressure inside the storage remains on the level of the chosen charging pressure (about 3.5 MPa). Hence, before connecting the storage to any gas using equipment it's necessary to release some little amount (few percent from total storage capacity) of stored gas and reduce the pressure at least till the acceptable maximum pressure level of your equipment (probably ≤ 1 MPa) .
This purging procedure, which takes only few seconds, will also release the gas impurities accumulated in the free space of the hydride-based storage making it much higher purity hydrogen source.
Metal Hydrides
SOLID-Hâ„¢ hydrogen storage containers are filled with metal powders that absorb and release hydrogen (metal hydrides). You may already be using metal hydrides in your laptop computer (nickel-metal hydride batteries).
The most popular SOLID-H containers supply a few atmospheres of hydrogen gas pressure at room temperature. This is the safest method known for storing flammable hydrogen gas. If your hydrogen system develops a leak, SOLID-H immediately releases a small fraction of its stored hydrogen. The remainder will be released over a period of hours.
Typical uses for SOLID-H include hydrogen supplies for gas chromatographs and fuel storage for hydrogen engines or fuel cells. A typical SOLID-H container is shown below.
SOLID-H Model CL-370A metal hydride hydrogen container holds 370 standard liters of hydrogen gas.
Like all SOLID-H containers, it has a pressure relief valve for safety and a quick connect coupling for convenience in connecting to your system.
Metal hydrides are the most compact way to store hydrogen (more dense than liquid hydrogen). The internal volume of the CL-370A is less than 0.7 liters. 370 liters of hydrogen capacity is more than 500 times the size of the container!
Standard SOLID-H BL-series containers hold 18, 20, 30, 120, 220 or 740 standard liters of hydrogen gas. These are on the shelf or available on short delivery schedules.
The lower cost SOLID-H CL-series containers, including CL-370 and CL-910, are based on aluminum industrial gas cylinders. These two containers hold 370 and 910 liters of hydrogen respectively. The aluminum cylinders used to make the CL-series are rated for very high pressures. This makes them heavier than equivalent thin walled stainless steel BL-series containers of comparable capacity.
If you need a different capacity or special pressure-temperature specifications, just contact our fuel cell specialists and we will get back to you as soon as possible.
How do I Use my SOLID-H Metal Hydride?
Using Your SOLID-H Hydride
A SOLID-Hâ„¢ container is coupled to your system by a fitting that you specify when you order. This is usually a quick connect for convenience of installation and removal. Unless you specify a different fitting we will install a Swagelok QM series female quick connect on the container. We also supply a mating male quick connect that adapts to 1/8 th inch tubing.
The hydrogen pressure when charging or discharging a SOLID-Hâ„¢ container is something you select when you order. Four standard pressure ranges are offered; Alloy A (1-10 bar at room temperature), Alloy L (2-3 bar at room temperature), Alloy M (4-5 bar at room temperature) and Alloy H (8-12 bar at room temperature).
Alloy A is an iron-titanium alloy that may be shipped void of hydrogen as non-hazardous material. Alloys L, M and H are rare earth-nickel alloys. After activation (activation means "charged for the 1st time") they must be shipped void of hydrogen as a flammable solid. The expense of hazardous shipping may be avoided if you order inactivated SOLID-Hâ„¢ containers. We will send activation instructions.
Recharge your SOLID-Hâ„¢ container by connecting it to a source of clean dry hydrogen gas at the pressure specified in your SOLID-Hâ„¢ manual. The container will get warm to the touch. When it is cool again, recharging is complete.
Reduce the pressure to the value indicated for your alloy in the SOLID-H TM manual before disconnecting it from your hydrogen source. Failure to do so may lead to venting through the pressure relief in hot environments (pressure increases rapidly with temperature).
Pressure Regulator
If your application requires low pressure hydrogen you will need a pressure regulator, like the one shown below.
Pressure Regulator, PR-50, sets the outlet pressure from 0-50 psig (0-3.4 bar gauge). Maximum inlet pressure is 300 psig (20 bar gauge). The outlet connection on the regulator has 1/8 NPT female pipe threads.
Metal Hydride (MH)
Metal Hydride hydrogen storage is a pretty cool technology where the Hydrogen molecule is actually adsorbed into a metal matrix. This results in gas storage densities that are higher than liquid hydrogen (on a volume basis). This makes metal hydrides great for applications that are restricted in space, but not in weight (or cost, usually). Metal hydrides typically store hydrogen at 4-8 weight %, not including storage vessel or other storage system requirements. This means 100 kg of MH material would store 4 – 8 kg of hydrogen. With the containment, balance of plant, etc, expect realistic numbers to be half of that.
The BL-120 metal hydride has a Hydrogen Capacity of 120-135 standard liters (4.6-5.19 scf) and a recharge time of ~9 hours.
Metal hydrides adsorb hydrogen at low to around room temperature and moderate pressure and release at higher temperatures. The exact temperatures/pressures depend on the specific metal hydride compound chosen. Since the metal hydrides release heat when they adsorb hydrogen, they must be cooled when being filled (some smaller systems may not need active cooling, just remember the bottle will get warmer and cooler, the faster it can adsorb the hydrogen). In order to get the most hydrogen from them, they must be heated to release the hydrogen. This all requires additional systems and controls.
But I still like the metal hydrides; the science is very cool to me and it is great for certain applications where you can afford to have a much heavier system in exchange for storing more hydrogen in a smaller space.
Check out all of the Metal Hydrides on our online store.
Boro Hydrides
The most common of these is Sodium Borohydride (NaBH4) , but there are a number of others. These are certainly very cool in theory, and I believe some companies are at or are ever close to commercial viability. Borohydrides have a pretty high hydrogen density and are actually one of the few hydrogen storage methods that are approved for use and transport on commercial aircrafts. Their two biggest drawbacks, in my experience (which, granted, is a bit limited) is that they use water and a catalyst to release the hydrogen which is impractical to re-fill/regenerate the Borohydride by use (must change cartridge).
The fact that it can’t be easily recharged by a user isn’t really that big of a problem if the supply chain is there to support it and you can go to your local Quickie Mart or Walmart and get refill cartridges. Or if you’re not a consumer application and can handle your own supply chain/logistics (i.e. military).
The needing of water and a catalyst to release the hydrogen has been a problem in many of the systems I have seen. The water and NaBH4 create kind of a slurry/mud that has a tendency to clog tubes and reactor chambers (where the catalyst is).
What Hydrogen Storage is Best for Me?
There are a number of different Hydrogen storage options available. The one which is best for you depends on what is most important for your application:
-
Compressed
-
Economical
-
Readily Available
-
-
Metal Hydride (MH)
-
High volumetric density (kg H2/ft3)
-
Heavy
-
May need more advanced controls (heat/cool, etc)
-
-
BoroHydrides
-
High volumetric density
-
Lighter than MH
-
FAA approved for use on commercial aircraft (i.e. passenger can carry on)
-
Complex systems
-
Compressed Hydrogen Cylinders
Compressed Hydrogen cylinders are usually the most readily available and economical solution. Usually, the most cost effective solution for testing or in some stationary applications is to simply rent/buy Hydrogen cylinders from your local gas supplier, often the local welding supplier has hydrogen readily available on short notice.
A Lincoln Composites Cylinder
If you are ready to integrate a more advanced tank into your system, you should consider composite H2 tanks from suppliers such as:Dynatek, Worthington (SCI), Lincoln Composites
These tanks are often Department of Transportation (DOT) certified (not always though, confirm with the manufacturer if you determine you need a DOT certified tank) and are lighter than the standard steel cylinders used by the gas supply shops. They are available in a variety of sizes (and pressure ratings) from the various manufacturers, and custom versions are also available if you are willing to pay extra. Be aware that lead time on these tanks are often quite long (6-8 weeks) unless you just happen to catch them with inventory (which doesn’t happen often). Some even come with integrated pressure regulators and safety valving, which is convenient.
What Else do I Need for my Fuel Cell?
AUGUST 6, 2012 BY FUELCELLSETC 2 COMMENTS
Your 5 kW Fuel Cell may not be all you need
So, you have bought a Fuel Cell and are ready to start using it.
Or are you?
Did you plan on any of the ancillary components you might need? Depending on who you buy the fuel cell from and what model it is will determine what components come with the fuel cell and what you will need to buy. In general, a fuel cell system needs several things in order for it to work in any system:
-
Hydrogen storage (which may also include H2 production)
-
Fuel Cell system
-
Power conditioning
Hydrogen Storage
Even if you are generating your hydrogen on-site, you will almost certainly need some hydrogen storage. There are several different options for storage, including:
-
Compressed H2 tanks
-
Liquid H2 tanks
-
Metal Hydrides
-
Other, less common storage methods (liquid storage, sodium borohydride, etc)
Each of these have their own advantages and are best suited for different applications (more on this another day). However, for most applications, Compressed H2 storage is the easiest, most economical and most readily available method. This could be simple H2 cylinders from your local welding or gas supply shop (be sure the purity is suitable for your fuel cell), or more advanced carbon fiber cylinders from suppliers likeDynetec, Worthington Cylinders (formerly SCI), Lincoln Composites, and others. Don’t forget to make sure you have a regulator to go from the tank pressure down to the operating pressure of the Fuel Cell (some tanks have these integrated, some don’t). You will probably also need a refueling port or at least a fitting to re-fill your tanks with.

Fuel Cell
There are many fuel cell manufacturers out there that make their own fuel cells systems such as Pearl Hydrogen, which you can buy from us; other hydrogen fuel cell companies include: Heliocentris, Horizon Fuel Cells, and Hydrogenics (among others -fuelcells.org has an excellent list of fuel cell companies). When reviewing each fuel cell system you need to be sure that you understand what each system includes in order to be certain that you will have everything you need to operate when your fuel cell system arrives.
Power Conditioning
Power conditioning is basically electronics that take the direct current (DC) voltage from the fuel cell which will fluctuate depending on the load and converts it into a stable voltage of your choosing (either AC or DC). Depending on the amount of power you are dealing with and your end requirements this could be as simple as a low-cost DC/DC converter or DC/AC inverter from any electronics shop to a full custom, multiple voltage power controller costing $20,000 and up.
Safety
You may also want some H2 sensors to detect any leaks and safely shut the system down if it does. Again, some fuel cell systems may incorporate these into their packaging, others may not. In any case, if you are putting the tank and/or fuel cell in any kind of enclosure, you will need sensors and safety equipment.
Note: Any inclusion of suppliers/manufacturers is not meant to be exhaustive or interpreted as an endorsement or recommendation of their products. These are all companies and suppliers that came to my mind first. I know there may be others in each category that could fit your requirements better than the ones I have listed. This is meant as a guide to help you get started.
Can I Purify Hydrogen from my HHO with a Metal Hydride?
We occasionally get questions from people wanting to know if they can use a Metal Hydride (MH) to purify the Hydrogen from an HHO generator, so I thought I would post our response here:
No
Why?
Putting HHO into a metal hydride container should not be done. Aside from the fact that it would be extremely unsafe to put HHO gas in a chamber with a cataylst (e.g. MH) since it will cause it to burn/explode, both Oxygen and humidity do irreparable damage to the MH. Do not use a MH to purify HHO.
HHO requires very special care when handling. It is, by it's very production technique, in perfect stoiciometric balance for combustion and simply needs an ignition source or catalyst to initiate the reaction – and Metal Hydrides are a catalyst for this reaction.
Most other methods of producing H2 are much safer. One methode is using PEM Electrolyzers (or almost any other method) - these are far safer because the Nafion membrane separates the H2 from the O2 and neither are ever together (unless there is a leak somewhere in the system). Electrolyzer MEAs are also more efficient than HHO, but are also quite a bit more expensive and can be a little more complex than simple metal plates in a jar.
Metal Hydrides can be used to purify Hydrogen in some cases, but it depends on the specific MH and the particular contaminates in the gas stream. In general, Moisture, Oxygen and Carbon Monoxide (CO) are among the contaminates that are detrimental to the Metal Hydride.
