In this paper, the state of the art of fuel cells for vehicles are reviewed. Based on the technology chain of vehicular fuel cells, the bottle-necks and research hot-points are elucidated in terms of materials, components and stacks. Particularly, the fuel cell materials include catalyst, ion exchange membrane and gas diffusion layer; the fuel cell components include membrane electrode assembly and bipolar plates; and the system components include air compressor, humidifier, hydrogen recirculation pump and hydrogen cylinder. Currently, some domestic FC materials have reached the standards of commercial products. The authors encourage industry partners to invest FC enterprises and build up relative production lines, promoting domestical FC technology progress.
