Zusammenfassung:	PURPOSE: To attain power generation having heat utilization system with excellent energy efficiency by a small and simple device by using high purity hydrogen obtained by reforming hydrocarbon by steam for power generation of a fuel cell, using offgas as fuel of a reformer, and also using exhaust gas heat. CONSTITUTION: Hydrocarbon is reformed by steam by a membrane reformer 5 having a hydrogen separable permeable film 4 by supplying natural gas 7 and steam 8. Electric power is generated by supplying high purity hydrogen 11 separated from generated reformed gas by the permeable film 4 to a fuel cell 12. On the other hand, offgas 6 of the reformer 5 is supplied to a combustor 3, and is burnt by air from a blower 2, and is used as a heat source of the reformer 5 and a steam generator 10. Combustion exhaust gas 13 of the reformer 5 is also used as a heating source of a heating heat source or a warm water supply device or the like.
