英文摘要：

The proton exchange membrane fuel cell（PEMFC）has many advantages such as high energy conversion efficiency,sustainability and cleanliness,and becomes preferred power sources for the next generation of electric vehicles.All aspects have made remarkable progress because more attention has been paid to fuel cell vehicle at home and abroad in recent years.In this paper,current status and research progress of key technologies of the proton exchange membrane fuel cell power system were introduced from four aspects of fuel cell vehicle：water and heat management system,control system,durability and cold-start.The relevant issues of fuel cell as vehicle power system commercialization,which need to be solved,are also expected.
