Abstract : A series of mixed transition metal oxide catalysts have been studied in order to replace presently used platinum catalysts for the air-oxygen electrode in alkaline electrolyte fuel cells, mechanically rechargeable zinc-air batteries, and primary 'disposable' zinc-air batteries. The catalytic materials are mixed oxides of metals like iron, copper, magnesium, cobalt, and alumimum which are inexpensive (compared to Pt) and yet effectively produce initial electrical performance characteristics comparable to the Pt metal catalysts.
