Provided is a power generation system capable of preventing water in a system from being frozen by supply air even when the outside air temperature is low, and an operation method thereof. The power generation system (100) includes an air supply channel (62), a fuel cell (14), a housing (11) for housing the fuel cell, a ventilator (air supply device) (15), and a housing A fuel cell system (10) having a supply air temperature detector (51) for detecting the temperature of the supply air, a combustion device (30) having a combustor (31), and combustion exhaust gas generated by the combustion device to the outside An exhaust gas flow path (61) for discharging and a control device (50) are provided. The air supply flow path and the exhaust gas flow path can exchange heat between the media flowing through the flow paths. The control device (50) activates the combustion device when the fuel cell system is activated and the temperature detected by the air supply temperature detector is equal to or lower than a predetermined first temperature. |
