| Zusammenfassung: | To provide a fuel cell system capable of suppressing unnecessary power generation with a fuel cell.SOLUTION: A fuel cell system 101 is configured so that a controller 201 which, when fully closing an inlet sealing valve 174, controls fully closing and opening to be controlled for establishing an opening degree of the inlet sealing valve 174 at a larger control fully-closing opening degree than 0° using a motor 32, and when the inlet sealing valve 174 determines that air is leaking while controlling a fully-closing opening degree to be controlled, corrects the fully-closing opening degree to be controlled to the closing side until such a zero position opening degree that air leakage amount is zero.SELECTED DRAWING: Figure 1
【課題】燃料電池での不要な発電を抑制できる燃料電池システムを提供する。【解決手段】本開示の一態様は、燃料電池システム１０１において、コントローラ２０１は、入口封止弁１７４を全閉にする場合、モータ３２により入口封止弁１７４の開度を０°よりも大きい制御全閉開度にする制御全閉開度制御を行い、制御全閉開度制御を行っているときに、入口封止弁１７４にてエアが洩れていると判断したときには、制御全閉開度をエアの洩れ量がゼロとなるゼロ位置開度まで閉弁側に補正する。【選択図】図１ |
