To avoid dispatch of a maintenance staff when an abnormal drainage error occurs under a low temperature environment.SOLUTION: A fuel cell system comprises: a reforming water tank 32 including a reforming water storage unit 32A which stores water obtained from an exhaust gas discharged from a fuel cell module as reforming water introduced into the fuel cell module; a discharged water storage unit 32B to which a first drainage 102 for storing water overflowing from the reforming water storage unit 32A and discharging the stored water to outside and a drainage piping 104 are connected; a surplus storage unit 32C to which a second drainage 105 for directly discharging the water overflowing from the discharged water storage unit 32B to outside is connected; and a control device including a control unit which stops at least a part of a local system when the abnormal drainage error is detected and a condition indicating that an outside environment temperature is relatively low is satisfied, and performs control for releasing the abnormal drainage error when a prescribed release condition is satisfied.SELECTED DRAWING: Figure 3 【課題】低温環境下で排水異常エラーが発生した場合に、メンテナンス員の出動を回避する。【解決手段】燃料電池システムは、燃料電池モジュールから排出される排ガスから得られる水を、燃料電池モジュールに導入する改質水として貯留する改質水貯留部３２Ａを含む改質水タンク３２と、改質水貯留部３２Ａからオーバーフローした水を貯留し、かつ、貯留した水を外部に排出する第１排水路１０２及び排水配管１０４が接続された排水貯留部３２Ｂと、排水貯留部３２Ｂからオーバーフローした水を直接外部に排出する第２排水路１０５が接続された余剰分貯留部３２Ｃと、排水異常のエラーを検知し、かつ、外部環境の温度が相対的に低温であることを示す条件を満たす場合に、自システムの少なくとも一部を停止し、所定の解除条件を満たす場合に、排水異常のエラーを解除する制御を行う制御部を含む制御装置と、を備える。【選択図】図３
