1. 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.
