This paper analyzes the development status of fuel cell basic materials，key components and fuel cell system in China. At present，the rapid development of automotive fuel cells in China has gradually entered the stage of commercialization. The galvanic pile and system have basically realized the replacement of domestic production，but the key materials and core components have not yet formed mass production. In the later stage，it is still necessary to increase R&D investment，strengthen the docking of upstream and downstream enterprises in the fuel cell industry chain，strengthen the construction of relevant supporting facilities，and need strong support from the government.
