CeO_2 was added to Pt/C catalyst in the cathode of PEMFC by both sol and impregnation methods. The samples were evaluated by TEM,cyclic voltammogram techniques and proton exchange membrane fuel cell performance test.

• 应用溶胶法和浸渍法向质子交换膜燃料电池阴极Pt/C催化剂添加CeO2；透射电子显微镜(TEM)分析和循环伏安测试表明:对由上述两种方法制备的各含5%25CeO2的Pt/C催化剂；其粒径、形态分布以及CeO2在催化剂表面的覆盖度都不相同.
