PROBLEM TO BE SOLVED: To obtain a characteristic more excellent than a proper characteristic of the original hydrogen storage alloy even in any point of intitial activation and the cycle service life. SOLUTION: A hydrogen storage alloy electrode is formed by joining particles A of first hydrogen storage alloy having a CaCu5 type structure and particles B of second hydrogen storage alloy having a Zr-Ni type Laves phase structure, and a joining layer C having the new composition containing componental elements of the first and the second hydrogen storage alloys is formed on the contact interface. |
