ABSTRACT:
A shaped body of hydrogen absorbing alloy prepared by pressing a mixture of a hydrogen absorbing alloy powder A having a first particle-size distribution, a hydrogen absorbing alloy powder B having a second particle-size distribution and a binder C, the powder A being larger than the powder B in mean particle size, the mixture being at least 0.03 to not gerater than 0.50 in the mean particle size ratio r.sub.B /r.sub.A of the powder B to the powder A wherein r.sub.A and r.sub.B are the mean particle sizes of the respective powders A and B. The hydrogen absorbing alloy of the powder B is higher than the hydrogen absorbing alloy of the powder A in the rate of progress of pulverization resulting from absorption and desorption of hydrogen.
