PROBLEM TO BE SOLVED: To suppress false detection as a high value for a pressure value in a tank.SOLUTION: A fuel cell system includes: a fuel cell; a tank for storing gas to be used for the fuel cell; a first pressure sensor for measuring charging pressure to be pressure in gas charging to a charging pipe for charging gas in the tank; a second pressure sensor for measuring supply pipe pressure to be pressure when starting the fuel cell in a supply pipe for supplying gas from the tank to the fuel cell; a temperature sensor for measuring an inner temperature of the tank; and a control unit for finding out an estimated pressure value of the supply pipe pressure on the basis of a first pressure value indicating the charging pressure when starting the fuel cell, the inner temperature when the first pressure value is measured and the inner temperature when the supply pipe pressure is measured and detecting a lower value out of the estimated pressure value and the second pressure value indicating the supply pipe pressure as supply pipe pressure.SELECTED DRAWING: Figure 3

    【課題】タンク内の圧力値が高く誤検出されることを抑制する【解決手段】燃料電池システムは、燃料電池と、燃料電池で用いられるガスを貯蔵するタンクと、タンクにガスを充填するための充填用配管におけるガス充填時の圧力である充填時圧力を測定する第1の圧力センサと、タンクから燃料電池にガスを供給するための供給用配管における、燃料電池の起動時の圧力である供給用配管圧力を測定する第2の圧力センサと、タンクの内部温度を測定する温度センサと、制御部であって、燃料電池の起動時に、充填時圧力を示す第1の圧力値と、第1の圧力値が測定された際の内部温度と、供給用配管圧力が測定された際の内部温度と、に基づき、供給用配管圧力の推定圧力値を求め、推定圧力値と供給用配管圧力を示す第2の圧力値とのうち、より低い値を、供給用配管圧力として検出する制御部と、を備える。【選択図】図3
