Hydrogen purification and storage system

Patent ·
OSTI ID:5496960
A method of purifying and storing hydrogen or otherwise separating hydrogen gas from a gaseous mixture containing hydrogen is disclosed. A mixture of hydrogen and other gaseous components is applied under pressure to a hydride container holding a hydride forming material adapted to adsorb at least hydrogen from the gaseous mixture. Cooling of the hydride forming material facilitates adsorption of hydrogen and other gases from the gas mixture. By selectively heating the hydride forming material, following the adsorption step, hydrogen and the other adsorbed gases are selectively released and can, thus, be separated from each other. If hydrogen is the only gaseous component of the gas mixture which is adsorbed during the adsorption step, then substantially pure hydrogen is obtained by heating the hydrogen-loaded hydride material sufficiently to release the purified hydrogen therefrom.
