Abstract
A hydrogen absorbing alloy electrode is provided which has an excellent oxygen gas absorbing capacity and further improved in charge-discharge cycle characteristics and high-rate discharge characteristics. The electrode contains a powder prepared by mixing a hydrogen absorbing alloy powder with a powder of at least one complex oxide selected from the group consisting of a ZrO —Y O solid solution, ZrO —CaO solid solution, CeO —Gd O solid solution, CeO —La O solid solution, ThO —Y O solid solution, Bi O —Y O solid solution, Bi O —Gd O solid solution, Bi O —Nb O solid solution and Bi O —WO solid solution. Preferably the electrode contains 0.1 to 10 wt. % of the complex oxide powder based on the combined amount of the two powders.
