A fuel cell system includes: a coolant circulation passage through which a coolant for cooling a fuel cell circulates; a pump that circulates the coolant; a radiation unit that cools the coolant by discharging heat from the coolant; a bypass passage connected to the coolant circulation passage so as to bypass the radiation unit; and an open/close valve that is provided in a convergence portion where low temperature coolant that has passed through the radiation unit and high temperature coolant that has passed through the bypass passage without passing through the radiation unit converge, and that opens when a temperature of the high temperature coolant reaches or exceeds a predetermined opening temperature, whereby the low temperature coolant and the high temperature coolant converge and are supplied thus to the fuel cell, wherein a basic discharge flow of the pump is calculated in accordance with a condition of the fuel cell, and when the temperature of the low temperature coolant is lower than a predetermined temperature, a discharge flow of the pump is increased above the basic discharge flow. |
