Abstract
Use of noble metal alloy catalysts, such as PtCo, as the cathode catalyst in solid polymer electrolyte fuel cells can provide enhanced performance at low current densities over that obtained from the noble metal itself. Unfortunately, the performance at high current densities has been relatively poor. However, using a specific bilayer cathode construction, in which a noble metal/non-noble metal alloy layer is located adjacent the cathode gas diffusion layer and a noble metal layer is located adjacent the membrane electrolyte, can provide superior performance at all current densities.
