PROBLEM TO BE SOLVED: To solve the problem of being incapable of accurately grasping temperature of coolant.SOLUTION: A fuel cell system comprises: a fuel cell; a coolant supply passage for supplying coolant to the fuel cell; a radiator for cooling the coolant; a first temperature sensor provided at an exit of the radiator to measure a temperature of the coolant; an ambient temperature sensor; and a control unit. The control unit estimates a temperature of the coolant flowing in the coolant supply passage, on the basis of an ambient temperature measured by the ambient temperature sensor; and adjusts a flow rate of the coolant by acquiring a temperature of the coolant flowing in the coolant supply passage on the basis of a temperature measured by the first temperature sensor, after it is estimated that the coolant staying at the radiator has reached the first temperature sensor.SELECTED DRAWING: Figure 3

    【課題】冷却液の温度を正確に把握できない。【解決手段】燃料電池システムは、燃料電池と、前記燃料電池に冷却液を供給する冷却液供給流路と、前記冷却液を冷却するラジエータと、前記ラジエータの出口に設けられ、前記冷却液の温度を測定する第1の温度センサと、外気温センサと、制御部と、を備える。前記制御部は、前記外気温センサで測定された外気温に基づいて、前記冷却液供給流路を流れる冷却液の温度を推定し、前記ラジエータに滞留する冷却液が前記第1の温度センサに到達したと推定された後は、前記第1の温度センサで測定された温度に基づいて前記冷却液供給流路に流れる冷却液の温度を取得して冷却液の流量を調整する。【選択図】図3
