Abstract
A system includes a radiator side flow path for supplying a coolant which has cooled a fuel cell stack to a radiator, a bypass flow path for allowing the coolant which has cooled the fuel cell stack to bypass the radiator, a thermostat valve for increasing a flow rate of the coolant flowing through the radiator side flow path in a case where the temperature of the coolant is high as compared to a case where the temperature of the coolant is low, and an electric heater for warming up the coolant. The electric heater is controlled based on an outside atmospheric pressure and on the temperature of the coolant such that the temperature of the coolant flowing into the fuel cell stack is raised in a case where the outside atmospheric pressure is high as compared to a case where the outside atmospheric pressure is low.
