PROBLEM TO BE SOLVED: To provide a fuel cell system in which durability can be enhanced at start-up.SOLUTION: The fuel cell system including a stack 11, and a combustor 21 for rising the temperature by supplying combustion gas to the stack 11 at start-up is further provided with a control unit 31 performing control for rising the temperature of the sack 11 by supplying combustion gas of the combustor 21 for start-up to the cathode 11a of the sack 11 in start mode, and for reducing the flow rate Fb of combustion gas being supplied to the stack 11 when the temperature of the stack 11 reaches a preset temperature equalization start temperature T1. Since the temperature of the stack 11 is equalized by such control of the control unit 31, deterioration and damage of the stack 11 due to variation in temperature distribution at start-up can be prevented. |
