PROBLEM TO BE SOLVED: To provide a technology capable of suppressing excessive drainage from a fuel cell.SOLUTION: A fuel cell system 100 comprises a drainage switch 11, control unit 15, fuel cell 20, and cathode gas supply unit 30. The control unit 15 has a function as a drainage processing execution unit 16 and a function as a water content detection unit 18. The drainage processing execution unit 16, when having accepted a drainage instruction from a driver through the drainage switch 11, executes air-scavenging processing of the cathode gas supply unit 30 supplying ambient air, as an air-scavenging gas, to the fuel cell 20 to discharge water from the inside of the fuel cell 20. The drainage processing execution unit 16 nullifies the drainage instruction from the driver or reduces a drainage amount from the fuel cell 20 by changing an execution condition of the air-scavenging processing, when a water content inside the fuel cell 20 acquired by the water content detection unit 18 is equal to or lower than a predetermined threshold.SELECTED DRAWING: Figure 1

    【課題】燃料電池からの過度な排水を抑制可能な技術を提供する。【解決手段】燃料電池システム100は、排水スイッチ11と、制御部15と、燃料電池20と、カソードガス供給部30と、を備える。制御部15は、排水処理実行部16としての機能と、含水量検出部18としての機能と、を有する。排水処理実行部16は、排水スイッチ11を介して運転者からの排水指令を受け付けたときには、カソードガス供給部30によって燃料電池20に掃気ガスとして外気を供給し、燃料電池20の内部から水分を排出させる掃気処理を実行する。排水処理実行部16は、含水量検出部18によって取得された燃料電池20内部の含水量が所定の閾値以下である場合には、運転者からの排水指令を無効にする。あるいは、掃気処理の実行条件を変更して、燃料電池20からの排水量を低減させる。【選択図】図1
