PROBLEM TO BE SOLVED: To provide a hydrogen storage alloy electrode whose electric conductivity and discharge capacity can be enhanced and which can maintain these in a high condition even if it passes through a hydrogen storage-release cycle. SOLUTION: Unpulversable hydrogen storage alloy powder is contained by 5 to 50wt.% in hydrogen storage alloy powder to form a hydrogen storage alloy electrode. Powder manufactured by a quenching coagulating method, powder having the nonstoichiometric composition or powder which has a CaCu5 type crystal structure and contains Co are used as the unpulversable hydrogen storage alloy powder. |
