摘要
Polymer electrolyte membrane fuel cells(PEMFCs), as an energy conversion technology, have attracted extensive attention due to their high conversion efficiency, low emission, high energy density,and fast fuel charging [1,2]. Pt-based catalysts have been acknowledged to be the most effective catalyst for the oxygen reduction reaction(ORR) [3–5]. However, both the source scarcity and high cost of Pt severely hinder the commercial application of the PEMFCs [1,6,7].
