Abstract: A review on the state-of-art in the world for fuel cell technology was given, which is an efficient,
clean, and new energy technology, including in China, northern America, European Union, Japan, South Korea
and so on. A comparison analysis was made in different aspects, such as the technical specifications of fuel
cell vehicles, the lifetime and the environmental adaptability of fuel cell engines, the hydrogen storage system,
the key materials, the auxiliary system of fuel cells, the demonstration of fuel cell vehicles and the infrastructure
of hydrogen refueling stations. The results show that global automobile companies are prepared for the
industrialization of fuel cell vehicles, and will enter mass production stage in 2015; while fuel cell vehicles are still
in the demonstration stage in China. The future hot points in next generation fuel cell vehicles are the cell life
extension, the system cost reduction, the hydrogen infrastructure construction, and commercial demonstration.

Key words: fuel cell vehicles, cell lefe extension, system cost, hydrogen infrastructure, demonstration projects
