The present invention provides a method for absorbing and releasing hydrogen which comprises applying repeatedly hydrogen pressurization and depressurization to a hydrogen storage metal alloy of a body-centered cubic structure-type phase exerting a two-stage or inclined plateau characteristic in a hydrogen storage amount vs hydrogen pressure relation in an appropriate fashion to absorb and release hydrogen, and at least at one stage during the release of hydrogen, making the temperature (T2) of the above-mentioned hydrogen storage metal alloy higher than the temperature (T1) of the hydrogen storage metal alloy during the hydrogen absorption process (T2 > T1), thereby enabling the release and utilization of occluded hydrogen at a low-pressure plateau region or an inclined plateau lower region, which has not been utilized in the prior art.

L'invention concerne un procédé d'absorption et de libération consistant à appliquer à plusieurs reprises une pression d'hydrogène sur un alliage de stockage d'hydrogène présentant une structure cubique à corps central et doté d'une propriété de plateau à gradient ou étage double en termes de rapport entre la quantité d'hydrogène absorbée et de la pression d'hydrogène et l'exposition de l'alliage à une pression réduite. Au cours de la libération d'hydrogène (T2) et pendant un certain laps de temps au moins, la température de l'alliage est inférieure à celle à laquelle se produit l'absorption d'hydrogène, T2 est donc supérieur à T1. Ce procédé permet la libération et l'utilisation de l'hydrogène stocké dans la zone de pression inférieure dans un plateau à étage double ou dans la zone de la partie inférieure d'un plateau à gradient.
