Zusammenfassung:	PROBLEM TO BE SOLVED: To restrain deterioration of power generation performance by controlling temperature of gas supplied to a fuel cell. SOLUTION: A fuel cell stack 1 has a heat exchange section 4 for performing heat exchange between mixed gas including primary supplied hydrogen and circulated gas and a coolant for controlling temperature of the fuel cell stack. A system control unit 40 adjusts temperature of the coolant so as to settle temperature of mixed supply hydrogen supplied to the fuel cell stack 1 by converging at a confluent section in a range of controlled temperature, as a temperature adjusting means is controlled on the basis of the temperature (tank temperature) Ttin of the primary supply hydrogen converging to the confluent section between the primary supply hydrogen and the circulated gas.
