Abstract
An alkaline battery includes a cathode, an anode, a separator, an alkaline electrolyte, and a hydrogen recombination catalyst. The hydrogen recombination catalyst includes a hydrogen oxidizing material, such as CuO, and an activating material. The activating material includes a first activating component and a second activating component. The components of the activating material can be Pd, Pt, Ru metals or salts thereof.
