摘要：

A series of PdCu/C catalysts were prepared using an improved impregnation method. The catalytic activities of the samples toward both the oxygen reduction reaction(ORR) and the hydrogen oxidation reaction (HOR) were characterized. Among these catalyts, Pd90Cu10/C exhibits the highest mass-specific catalytic activity toward the ORR, and Pd80Cu20/C is the best for the HOR. Single cell with Pd90Cu10/C as the cathode catalyst and Pd80Cu20/C as the anode catalyst was tested. The maximum power density of the cell is 204 mW/cm(2).
