Beschreibung
Zusammenfassung:	A combined power generation system according to an embodiment of the present invention includes a gasifier that is supplied with coal and oxygen to produce synthesis gas; a first reactor that produces hydrogen by using the generated synthesis gas; a natural gas synthesis device that has a methanization reactor which synthesizes methane by using the generated hydrogen; a fuel cell device that produces electric energy by receiving the supply of a methane-containing fuel from the natural gas synthesis device; and a separation membrane device that separates hydrogen from mixed gas which is discharged from the fuel cell device to supply the hydrogen to the first reactor.
