摘　　要：分别采用H2O2和H2SO4体系对Pt/C电催化剂的耐久性进行了加速实验研究,结果表明,H2O2会降低Pt/C电催化剂的团聚度,H2SO4则不会对Pt/C电催化剂的团聚度产生显著影响。H2O2加速实验对C载体造成的腐蚀作用明显,H2SO4加速实验会导致较多铂流失。H2O2 and H2 SO4 accelerating system were adopted to make a research for the durability of Pt/C electrocatalyst respectively. The results showed that H2O2 produced a remarkable decrease in the agglomeration of Pt/C electrocatalyst, while H2SO4 not. H2O2 could also make destroy of C support, as H2SO4 accelerating system made a comparatively large amount of Pt/C loss.
