Hydrogen is stored at cryogenic temperatures by adsorption on porous carbon having a nitrogen BET apparent surface area above about 1500 m.sup.2 /g. Hydrogen can be adsorbed and desorbed in the context of a cryopump, having as the pumping element a panel, having large particles of pressed porous carbon...http://www.google.fr/patents/US4580404?utm_source=gb-gplus-shareBrevet US4580404 - Method for adsorbing and storing hydrogen at cryogenic temperatures
