A fuel cell system includes a fuel cell (29) supplied with gas including hydrogen and gas including oxygen, a humidifying mechanism (73, 31) humidifying either one of the gas including the hydrogen and the gas including the oxygen or both of such gases using water from a water tank (19), a water collection mechanism (73, 31) collecting water from the fuel cell to return the water collected with the water collection mechanism to the water tank, an atmospheric temperature sensor (69) sensing an atmospheric temperature, and a controller (57) performing a high temperature control to increase an exhaust including steam to be expelled outside the fuel cell system when the atmospheric temperature sensed by the atmospheric temperature sensor exceeds a given temperature.
