摘要
Abstract
The oxygen reduction reaction at the cathode is one of the core reactions in fuel cells.How-ever,factors such as the slow cathode oxygen reduction reaction and the limited mass transfer will re-strict the improvement of battery performance and hinder the commercial application of proton ex-change membrane fuel cells.This article reviews the effect of catalyst,carbon support and ionomer in cathode catalyst layer on the activity of oxygen reduction reaction and the optimization strategies in recent years.By regulating the morphology of Pt catalyst and developing Pt-transition metal alloys,the number of active sites can be increased and the energy barrier of oxygen reduction reaction can be reduced.Non-platinum series catalyst can significantly reduce cost while enhancing the activity of oxygen reduction reaction through their unique structures(such as core-shell,porous structure,etc.)and active sites(such as Fe-N4).In addition,carbon support with a good pore size distribution can promote mass transfer,and modification strategies such as heteroatom doping further enhance the stability of the catalyst.The use of short side chains or highly oxygen-permeable ionomer can not only reduce the toxicity to the active site but also enhance the mass transport,further enhancing the activity of the oxygen reduction reaction.This article aims to provide guidance for the design of high-performance cathode catalyst layer.关键词
