摘要

1 Introduction As the best electrocatalyst,platinum (Pt) and Pt-based nanomaterials have been widely used in fuel cells,such as proton exchange membrane fuel cells (PEMFCs) [1,2].However,in the acid electrolyte,the low pH presents a highly corrosive effect on Pt-based materials on the cathode of PEMFCs,which can make Pt electrocatalysts easily dissolve in the solution under operating conditions [3-5].
