PALLADIUM ALLOY CATALYSTS FOR FUEL CELL CATHODES AND A METHOD OF PREPARING THE SAME

摘要

The object of the invention is to prepare a cathode catalyst for low and medium temperature fuel cells. This catalyst exhibits a catalytic activity as good, or better, than commercial Pt for oxygen reduction reaction (ORR) in acid medium, a good tolerance to methanol and a low production cost. This catalyst comprises an alloy containing a metal (Pd) and a non-metal (P or B). The process of the alloy production comprises the direct deposition of the catalyst on a gas diffusion layer substrate by a chemical method.
