Summary:To suppress deterioration due to potential variation of a fuel cell while suppressing stay of water in the fuel cell in a fuel cell system.SOLUTION: A fuel cell system FCS includes: a fuel cell FC; an air compressor ACP; and a control section CNT which controls an operation of the air compressor ACP. The control section CNT controls the operation of the air compressor ACP so that power requested by a load is supplied from the fuel cell system FCS to the load under a normal condition and controls the operation of the air compressor ACP so that the power requested by the load is supplied from the fuel cell system FCS to the load and a flow rate of oxidant gas to be supplied to the fuel cell FC becomes a prescribed flow rate or more under a prescribed condition different from the normal condition.SELECTED DRAWING: Figure 1 【課題】燃料電池システムにおいて、燃料電池内の水の滞留を抑制しつつ、燃料電池の電位変動による劣化を抑制する。【解決手段】燃料電池FCと、エアコンプレッサACPと、エアコンプレッサACPの動作を制御する制御部CNTとを備えて燃料電池システムFCSを構成し、制御部CNTは、通常条件下において、負荷から要求される電力が燃料電池システムFCSから負荷に供給されるように、エアコンプレッサACPの動作を制御し、通常条件と異なる所定条件下において、負荷から要求される電力が燃料電池システムFCSから負荷に供給されるように、かつ、燃料電池FCに供給される酸化剤ガスの流量が所定流量以上になるように、エアコンプレッサACPの動作を制御する。【選択図】図1
