<P>PROBLEM TO BE SOLVED: To provide a fuel cell power generation system and an operation method thereof wherein efficient power generation is possible. <P>SOLUTION: The fuel cell power generation system includes a fuel cell having a fuel electrode and an oxidizer electrode, a supply means by which the fuel gas is supplied to the fuel electrode, a temperature raising means by which oxidizer gas is raised to a temperature higher than that of the oxidizer gas and lower than that of the fuel cell and in which the oxidizer gas raised in the temperature is supplied to the oxidizer electrode, an exhaust gas recovery means by which at least one part of oxidizer electrode exhaust gas exhausted from the oxidizer electrode is recovered, a heat exhaustion means by which the temperature of the oxidizer electrode exhaust gas recovered by the exhaust gas recovery means is lowered, an air-cooled gas mixing means by which the oxidizer electrode exhaust gas lowered in the temperature by the heat exhaustion means is mixed with air-cooling gas supplied from the exterior to form mixed gas of which the temperature is lower than that of the oxidizer electrode exhaust gas lowered in the temperature, and an air-cooling type cooling means by which the fuel cell is cooled using the mixed gas formed by the air-cooled gas mixing means. <P>COPYRIGHT: (C)2010,JPO&INPIT |
