PURPOSE:To obtain a hydrogen storage electrode having less charge/discharge cycle number and easy to activate in its initial stage by heating the hydrogen storage electrode in vacuum or hydrogen atmosphere. CONSTITUTION:A produced hydrogen storage electrode is heated in vacuum or hydrogen atmosphere. Namely, it is supposed that, by the heat treatment in vacuum or hydrogen atmosphere, the gas molecule mainly consisting of oxygen adsorbed on the particle surface of a hydrogen storage alloy or hydrogenated material is removed, and storage/release of hydrogen is rapidly performed. Thus, the initial activation of the hydrogen storage electrode can be easily performed, and several-time repeat of charge and discharge is sufficient. |
