【摘要】 本文研究了WC对Pt类质子交换膜燃料电池催化剂性能的影响,采用还原煅烧方法制备得到WC, 将其加入常规Pt／C催化剂中,利用循环伏安作为表征方法,将加入前后的催化性能进行比较。结果显示, 随着WC的加入,催化剂在酸性介质中的性能得到有效改善;在甲醇溶液中的催化过程发生改变。更多还原

【Abstract】 In this work,an experimental study of the effect of adding WC to typically Pt/C catalyst for PEMFCs was carried out. The WC synthesized by reduced calcine method was mixed with the Pt/C catalyst and characterized by TEM and cyclic voltammetry techniques. The results show that the performance of the mixed catalyst especially the anti-methanol effect is better than the pure Pt/C catalyst.更多还原
