Research progress of Pt and Pt-based cathode electrocatalysts for proton-exchange membrane fuel cells
文献摘要:
Proton-exchange membrane fuel cells(PEMFCs)have been widely used commercially to solve the energy crisis and environmental pollution.The oxygen reduction reaction(ORR)at the cathode is the rate-determining step in PEMFCs.Plat-inum(Pt)catalysts are used to accelerate the ORR kinetics.Pt's scarcity,high cost,and instability in an acidic environment at high potentials seriously hinder the commercialization of PEMFCs.Therefore,studies should explore electrocatalysts with high catalytic activity,enhanced stability,and low-Pt loading.This review briefly introduces the research progress on Pt and Pt-based ORR electrocatalysts for PEMFCs,including anticorrosion catalyst supports,Pt,and Pt-based alloy electro-catalysts.Advanced preparation technology and material characterization of Pt-based ORR electrocatalysts are necessary to improve the performance and corresponding reaction mechanisms.
