Abstract: Fuel cell vehicles are considered to be the development direction of new energy vehicles in the future due to their advantages of "high efficiency, cleanliness, and zero emission." At present, most of the major automobile companies in the world have completed the basic performance research and development phase of fuel cell vehicles, and China's fuel cell vehicle technology research and development has also made significant progress. This paper analyzes the application status and characteristics of power system of domestic and foreign fuel cell passenger cars, buses and logistics vehicles. At the same time, the energy management strategies adopted by current fuel cell vehicles are reviewed, and the future development of fuel cell electric vehicles is discussed.
