PROBLEM TO BE SOLVED: To provide a technique for enhancing drainage of a fuel cell mounted on a mobile.SOLUTION: A fuel cell system 100 is mounted on a fuel cell vehicle 110, and includes a control unit 10, a fuel cell 20, an anode gas supply unit 50, and an inclination angle detector 70. The anode gas supply unit 50 circulates gas remaining in the anode side gas channel of the fuel cell 20 and piping 51, 61, 63, as scavenging-gas, by driving a hydrogen circulation pump 64. The scavenge unit 15 of the control unit 10 performs second scavenge control, when an inclination angle acquired by the inclination angle detector 70 is such an angle that an anode side outlet of the fuel cell 20 faces upward in a gravity direction. In the second scavenge control, the hydrogen circulation pump 64 is driven with a first number of revolutions Rin a first period P, and then the number of revolutions of the hydrogen circulation pump 64 is increased to a second number of revolutions Rin the first period P.SELECTED DRAWING: Figure 3
【課題】移動体に搭載されている燃料電池の排水性を高める技術を提供する。【解決手段】燃料電池システム100は、燃料電池車両110に搭載されており、制御部10と、燃料電池20と、アノードガス供給部50と、傾斜角度検出部70と、を備える。アノードガス供給部50は、水素循環用ポンプ64を駆動させることによって、燃料電池20のアノード側のガス流路内および配管51,61,63内に残留しているガスを掃気ガスとして循環させる。制御部10の掃気処理実行部15は、傾斜角度検出部70によって取得した傾斜角度が燃料電池20のアノード側の出口が重力方向上側に向く角度である場合に、第2掃気制御を実行する。第2掃気制御では、第1期間P1aにおいて第1回転数R1aで水素循環用ポンプ64を駆動し、第1期間P1aにおいて水素循環用ポンプ64の回転数を第2回転数R2aに増大させる。【選択図】図3
