In order to improve the efficiency of a fuel cell power generation system and its ability to adjust to disturbing factors which may occur during operation, a motor driven compressor for providing reaction air to the fuel cell system is driven independently of a power recovery system which recovers energy lost in operational by-products and converts the energy into electrical power. The independent motor driven compressor provides a stable supply of reaction air to the fuel cell and aids in shortening the time necessary for system start up.

A fuel cell power generation system comprising: a fuel cell; fuel reformer means coupled to said fuel cell for supplying fuel gas; motor driven compressor means coupled to said fuel cell for supplying pressurized reaction gas to said fuel cell; and power generator means including turbine means arranged for utilization of energy recovered from by-product fluids resulting from operation of the fuel cell system for secondary power generation; whereby, improved efficiency is achieved by providing a stable supply of pressurized reaction gas from a compressor driven by power from an external power system and by returning power to the external power system from a secondary power generator driven by a turbine using energy recovered by by-products of operation of the fuel cell system.
