摘要： The invention intends to provide a hydrogen storage alloy that can absorb and release hydrogen effectively at room temperature and shows excellent hydrogen storage amount and effective hydrogen transfer amount and furthermore shows excellent endurance.A pulverized hydrogen storage alloy powder is heated at 600° C. or more and 1200° C. or less for 10 min to 30 hr to apply strain relief annealing. A particle diameter of the hydrogen storage alloy powder is desirably 10 μm or less and the hydrogen storage alloy is desirably mainly composed of a BCC phase. Since the initial strain ahead of the hydrogenation is removed, a solid solution region of hydrogen is largely reduced and an initial hydrogen storage amount and an effective hydrogen transfer amount are increased. Owing to the pulverization, the strains are largely reduced from accumulating and propagating, the strains at the hydrogen storage are largely reduced from generating, an absorption plateau is largely increased, in addition thereto, the deterioration rate due to repetition of hydrogen storage and release can be largely improved.
