A power generation system includes a fuel cell unit, a combustion apparatus, and a controller. The fuel cell unit includes a fuel cell, a casing, a ventilation fan (an air supply device), and a temperature detector configured to detect the temperature of outside air supplied to the casing. An air supply passage through which the outside air is supplied to the casing, and a discharge passage through which a flue gas from the combustion apparatus is discharged, are configured in such a manner as to allow a medium flowing through the air supply passage and a medium flowing through the discharge passage to exchange heat with each other. When the fuel cell unit is to be started up, if the temperature detected by the temperature detector is lower than or equal to a predetermined first temperature and the combustion apparatus is not in operation, the controller refrains from causing the fuel cell unit to operate. |
