To provide a fuel cell system capable of shortening time until a vehicle is allowed to travel.SOLUTION: A fuel cell system mounted on a vehicle capable of traveling with electric power of a secondary battery even if power generation of a fuel cell is impossible at the time of starting a vehicle, includes the fuel cell, the secondary battery, and a control unit. The control unit calculates discharge permission energy of the secondary battery at the time of power generation pre-processing of the fuel cell and when there is a travel request of the vehicle at an output of the secondary battery from the fuel cell, calculates travel permission delay request time necessary from a travel request to travel permission of the vehicle from the discharge permission energy, and measures travel permission delay time that is an elapsed time from the travel request of the vehicle. The control unit allows travel of the vehicle when a value of the travel permission delay request time becomes smaller than a value of the travel permission delay time.SELECTED DRAWING: Figure 1 【課題】車両の走行許可が得られるまでの時間を短縮することができる燃料電池システムを提供する。【解決手段】車両の始動時に、燃料電池の発電が不可能であっても二次電池の電力で走行可能な車両に搭載された燃料電池システムであって、前記燃料電池と、前記二次電池と、制御部と、を有し、前記制御部は、前記燃料電池の発電前処理時、且つ、前記燃料電池からの前記二次電池の出力での前記車両の走行要求があった際に、前記二次電池の放電許可エネルギーを算出し、当該放電許可エネルギーから、前記車両の走行要求から走行許可までに必要な走行許可遅延要求時間を算出し、且つ、前記車両の走行要求からの経過時間である走行許可遅延時間を計測し、前記制御部は、前記走行許可遅延要求時間の値が前記走行許可遅延時間の値よりも小さくなった際に前記車両の走行を許可する、ことを特徴とする燃料電池システム。【選択図】図１
