The energy conversion efficiency of fuel cells is 2~3 times higher than that of internal combustion engines, so fuel cell vehicles are an ideal vehicle in terms of energy utilization and environmental protection.

Individual fuel cells must be combined into fuel cell groups in order to obtain the necessary power to meet the requirements of vehicle use.

Fuel cell technology has made significant progress in recent years. The world’s leading automobile manufacturers, such as DaimlerChrysler, Ford, Toyota and General Motors, have announced plans to bring fuel cell vehicles to market by 2004. At the present time, prototype fuel cell cars are being tested and fuel cell-powered transportation buses are undergoing demonstration projects in several North American cities. Technical challenges remain in the development of fuel cell vehicles, such as integration of fuel cell packs, improving fuel processors for commercial electric vehicles and auxiliary department car manufacturers are working toward integrating components and reducing component costs, and have made significant progress.

Compared with conventional vehicles, fuel cell vehicles have the following advantages.

1. Zero or near-zero emissions.
2. Reduced water pollution from oil leaks.
3. reduced greenhouse gas emissions.
4. Improved fuel economy.
5. Improved engine combustion efficiency.
6. Smooth and noiseless operation.
