It is wise not to say "can't" in our evolving science, my friends. From the first fuel cell design in 1801 (that's 214 years ago), much of this has been considered, designed, and tested. The link above is current, and the link below shows fuel cell history.
To store hydrogen into a cylinder tank:1. Hydrogen must be remove from all oxygen making hydrogen an inert gas form.2. Hydrogen must be liquefied at temperature of 20.28 K (−423.17 °F/−252.87°C) and maintained at this temperature so it does not turn into gas form by means of nitrogen.3. Hydrogen; maintenance of liquid state and the devices in order to do this requires an industrial MAZMAT type licensing and certification. This can only be acquired if undersigned by corporate entity with engineering degree with over-sight. Liquid hydrogen requires cryogenic storage technology such as special thermally insulated containers and requires special handling common to all cryogenic fuels. Liquid hydrogen is in all purposes considered an explosive in liquid form or gas form and certifications are not for public use.4. Hydrogen; if you do not storage H2 in liquid form, or gas form and have proper ventilation is still considered illegal for vehicular combustion volume metric efficiency usage in public highway motor applications, but currently is not enforced. As a private citizen on a public highway using water-hydrogen-cell for hydrogen+oxygen mix usage is considered an explosive do to oxygen in gas line with H2/Hydrogen. If hydrogen is introduced into combustion chamber without oxygen mixture then it is inert until contact with oxygen, therefore none explosive till that O2/Oxygen contact point of gas mixture. If hydrogen is introduced in combustion cylinder chamber as only hydrogen then it is considered legal if done by qualified professional certified by DOT/Department of Motor Vehicles, but again these laws are not in effect. Thus, do not become a poster child/adult as an example for the enforcement of these law awaiting to take effect. Therefore, do not ruin this new H2 application to further your fuel economy, please be careful and be certain hydrogen will not have any areas to pocket in engine compartment awaiting an ignition point explosive. ---Please Be Careful, and Be safe. Think of others in your science project.
could you clarify what you mean by "return to gas form by means of nitrogen"?
Hydrogen is NOT an inert gas, regardless of form.
You do NOT need an engineering degree to handle liquified gases, including hydrogen. (The key mistake here is "engineering degree")
Do you just make this up or are you paraphrasing (badly) some other source?
can i storage on a big hard balloon and connect to a little stove heater just for a evening cooking ? last time i make hydrogen (electrolysis) i use a regular balloon for storage and i connect a firefighters like hose (smaller scale of course) and i fire up like a torch for like one minute and was fun until balloon was empty :). i guess i can do same with bigger maybe cylindrical balloon (human size could be) and cook something. sorry my bad english
Ahh the danger of speaking in absolutes. Here is a fellow doing it in a residential setting on a large scale - albeit at low pressure/high volume. Really gets the imagination going....
Could you store it in a a propane tank for a grill, or maybe a refrigerant tank?
