摘　　要：To meet the sharp increase in demand for clean and renewable energy,it is necessary to develop new energyconversion and storage technologies,such as proton exchange membrane fuel cells(PEMFCs)and metal-air/oxygen batteries(MABs).Due to the sluggish reaction kinetics of the oxygen reduction reaction(ORR)and the oxygen evolution reaction(OER)in the cathodes of PEMFCs and MABs,significant amounts of precious metal catalysts need to be used,driving up the cost of fuel cells and MABs and thereby hindering their commercialization on a large scale.Transition metal and nitrogen co-doped carbonaceous catalysts(M/N/C)have high catalytic activity towards the ORR and OER once the catalysts are modified with certain promoters/additives.In addition,M/N/C catalysts can be prepared from abundant,inexpensive materials,making their cost negligible compared with precious metal catalysts,a development that would efficiently decrease the cost of PEMFCs and MABs.In last decade,numerous researchers have attempted to realize these applications of M/N/C catalysts,and some exciting results have been achieved,making these promising replacements for precious metal catalysts.However,some serious problems and significant challenges remain.In this paper,we review the research on the application of M/N/C analogue catalysts in PEMFCs and MABs in the last 10 years,indicate the remaining challenges,and suggest the future research directions.
