Zusammenfassung: | To provide a fuel cell system capable of warming up a fuel cell by efficiently utilizing heat of a secondary battery.SOLUTION: There is provided a fuel cell system for vehicles which includes a fuel cell and a secondary battery. The fuel cell system includes: a first cooling passage where a coolant to cool the fuel cell flows; a second cooling passage where a coolant to cool the secondary battery flows; a connection passage connecting between the first cooling passage and the second cooling passage; an on-off valve opening/closing the connection passage; and a control unit controlling the on-off valve. The control unit determines whether freezing occurs in the fuel cell, and, when it is determined that the freezing occurs, the control unit opens the on-off valve, and supplies a coolant from the second cooling passage to the first cooling passage.SELECTED DRAWING: Figure 1
【課題】二次電池の熱を効率的に利用し燃料電池を暖機可能な燃料電池システムを提供する。【解決手段】燃料電池システムは、燃料電池と二次電池とを有する車両の燃料電池システムであって、前記燃料電池を冷却する冷媒が流れる第1冷却通路と、前記二次電池を冷却する冷媒が流れる第2冷却通路と、前記第1冷却通路と、前記第2冷却通路と、を接続する接続通路と、前記接続通路を開閉する開閉弁と、前記開閉弁を制御する制御部と、を備える。前記制御部は、前記燃料電池に凍結が発生しているか否か判断し、前記凍結が発生していると判断した場合、前記開閉弁を開き、前記第2冷却通路から前記第1冷却通路に冷媒を供給する。【選択図】 図1 |
