摘　　要：用改良的浸渍法合成了多种不同合金度的碳载PdCu纳米粒子,考察其对氧还原和氢氧化反应的催化行为,并择优应用到质子交换膜燃料电池(PEMFC)中.研究发现,阳极采用Pd80Cu20/C催化剂,阴极采用Pd90Cu10/C催化剂组装的单电池在65℃下最大功率密度接近204 mW/cm2.A series of PdCu/C catalysts were prepared using an improved activities of the samples toward both the oxygen reduction reaction （ORR） impregnation method. The catalytic and the hydrogen oxidation reaction （HOR） were characterized. Among these catalyts, Pd90CU10/C exhibits the highest mass-specific catalytic activity toward the ORR, and PdsoCu20/C is the best for the HOR. Single cell with Pd90Cu10/C as the cathode catalyst and PdsoCu20/C as the anode catalyst was tested. The maximum power density of the cell is 204 mW/cm^2.
