Proton exchange membrane fuel cells(PEMFC)can be used in vehicle engines,new energy conversion devices with fixed or portable power sources,etc.It has the advantages of high efficiency,no pollution and fast start-up speed.Pt-based catalyst is an effective catalyst for oxygen reduction reaction(ORR).However,the limited resources,high price and high loading of Pt limit the large-scale application of PEMFC.The Pt-based catalyst in the catalytic process by changing the catalyst composition and carrier characteristics to achieve better catalytic effect is reviewed.These methods can improve the activity of the catalyst while reducing the Pt content,making the Pt-based catalyst cheap and stable.
