A method of absorption-desorption of a hydrogen storage alloy, characterized in that the temperature (T2) of the hydrogen storage alloy in the last stage of a hydrogen desorbing step is a temperature higher than the temperature (T0) of the alloy in a hydrogen absorbing step and the temperature (T1) of the alloy in the initial stage of the hydrogen desorbing step (that is, T2 > T1 >/= T0); and a hydrogen storage alloy which has a general formula TixCryMz wherein M represents one or more elements belonging to IIa, IIIa, IVa, Va, VIa, VIIa, VIII, IIIb and IVb Groups of the Periodic Table, 20 </= X + Y < 100 atomic %, 0.5 </= Y/X </= 2, and 0 < Z </= 80 atomic %, and contains oxygen and nitrogen inevitably included and spinodal decomposition phase in a minimum amount which forms inevitably. The method can be used for easily desorbing the absorbed hydrogen in the low pressure region of a PCT curve, which hydrogen has not been desorbed and accordingly not been used in the prior art. The method can be performed by the use of the above hydrogen storage alloy. |
