Abstract
The invention disclosed is a catalyst composition for an air cathode for use in an electrochemical cell, in particular in alkaline electrolyte metal-air e.g. zinc-air, fuel cells. The catalyst composition comprises an active material CoTMMP and silver, supported on carbon wherein the ratio of silver to CoTMPP is 1:1 to 2.4:1. Optional ingredients include a hydrophobic and a hydrophobic bonding agent, MnO, WC/Co or both. The catalyst composition is supported on microporous support layer and nickel foam or mesh to form an air cathode.
