Zusammenfassung:	PURPOSE: To improve the power generation efficiency for the unit fuel by driving a steam turbine for power generation with the steam generated by a boiler, and feeding the high-purity hydrogen obtained by a reforming device provided with a hydrogen-separating transmission membrane and using boiler waste heat as a heating source to a fuel cell. CONSTITUTION: A steam turbine 6 is driven by a steam 5 generated by a boiler 4 for power generation. The waste steam is condensed by a condenser 16, (supply) water 13 is added, and the water is circulated to the boiler 4 via a waste heat recovery boiler 10. The waste heat of the boiler 4 is utilized as the heating source of a membrane reactor 8 having a hydrogen separating transmission membrane. The steam 17 from a waste heat recovery boiler 10 and natural gas 18 are used as raw materials and are reformed at about 400-650 deg.C via a reforming catalyst, and the generated hydrogen is refined by the hydrogen- separating transmission membrane, e.g. a paladium-containing alloy thin film. The obtained high-purity hydrogen 11 is fed to a solid high polymer fuel cell 12 for power generation.
