Hydrogen absorbing alloy electrode and process for producing same
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 ZrO2&#8212;Y2O3 solid solution, ZrO2&#8212;CaO solid solution, CeO2&#8212;Gd2O3 solid solution, CeO2&#8212;La2O3 solid solution, ThO2&#8212;Y2O3 solid solution, Bi2O3&#8212;Y2O3 solid solution, Bi2O3&#8212;Gd2O3 solid solution, Bi2O3&#8212;Nb2O3 solid solution and Bi2O3&#8212;WO3 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.
