外文摘要：Proton exchange membrane fuel cells(PEMFCs),which have the advantages of high-power density,zero emission,and low noise,are considered ideal electrochemical conversion systems for converting hydrogen(H2)and oxy-gen(O2)/air into electricity.However,the oxygen reduction reaction(ORR),which is accompanied by multiple electrons,results in voltage loss and low conversion efficiency of PEMFCs.Currently,PEMFCs mainly use high-load precious platinum(Pt)to promote the ORR process;however,the high cost of Pt hinders the widespread commercialization of PEMFCs.Over the past few years,metal-nitrogen-carbon single-atom catalysts(M-N-C SACs)have attracted considerable attention and have been recognized as potential Pt-based catalysts owing to their outstanding ORR activity.This review briefly introduces the components of PEMFCs.Second,we discuss the catalytic mechanisms of the M-N-C SACs for the ORR.Third,the latest advances in noble,non-noble,and heteroatom-doped M-N-C SACs used as ORR and PEMFCs cathode catalysts are systematically reviewed.In sum-mary,we have outlined the current challenges and proposed a future perspective of M-N-C SACs for PEMFCs cathodes.
