A method of absorption-desorption of a hydrogen storage alloy, characterized in that the temperature (T2) of a hydrogen storage alloy in the last stage of a hydrogen desorbing step is a temperature higher than the temperature (T1) of the alloy in the initial stage of the hydrogen desorbing step (that is, T2 > T1), and said temperature (T2) in the last stage is a temperature such that the hydrogen pressure on the demarcation point of the plateau region of a PCT curve and the slope region adjacent to it is 0.08 MPa or higher at the temperature. REFERENCE:
Procédé d'absorption-désorption d'un alliage accumulant l'hydrogène caractérisé par le fait que la température (T2) d'un alliage accumulant l'hydrogène dans le dernier stade d'une étape de désorption d'hydrogène est supérieure à la température (T1) de l'alliage au stade initial de cette étape de désorption d'hydrogène (c'est-à-dire, T2 > T1) et que ladite température T2 de ce dernier stade est telle que la pression d'hydrogène au point de démarcation de la zone plane d'une courbe PCT et de la zone de pente contiguë à cette dernière est égale ou supérieure à 0,08 MPa à cette température.
