In video “Reversible “Hydrogen” Fuel Cell” I try to make a home made fuel cell from available materials. The reversible fuel cell make some hydrogen and oxygen when I apply some current to the cell (reverse action /electrolysis of water). A carbon material store some of the hydrogen by adsorption. After some time I disconnect the power supply and connect some load to the fuel cell (el. motor 3V/300mA). Better fuel cell you will get if you use some catalyst like platinum, cobalt / cobalt oxide, iridium, etc. But in this case these catalyst are expensive. You can also use some small amount of graphene or carbon nanotubes if you want.
