Abstract

Abstract: In order to design Pt‐free efficient cathode catalyst and promote the commercialization of fuel cells, different atomic ratio of carbon‐supported Pd‐W alloy catalysts were developed for oxygen reduction reaction (ORR). X‐ray diffraction (XRD) results show the Pd‐W alloys have the similar lattice characteristics to pure Pd. Transmission electron microscopy (TEM) and energy‐dispersive X‐ray spectroscopy (EDS) results show that the Pd‐W alloys disperse on the surface of carbon support uniformly. The results of the electrochemical tests show that the Pd19 W/C has two‐fold mass activity over Pd/C, which is hopeful for the application as low‐cost cathode catalyst.
