Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent a fuel cell from being deteriorated due to oxidant gas when the fuel cell stops power generation.SOLUTION: A control unit 15 of a fuel cell system 1 includes a reforming water supply control section controlling to supply reforming water to an evaporation section 32 by a reforming water pump 11b1 on the basis of temperature detected by a temperature sensor 36 in performing a stop operation of the fuel cell system (steps S108, S110).SELECTED DRAWING: Figure 2 【課題】燃料電池の発電が停止したときに、燃料電池が酸化剤ガスによって劣化しないようにする。【解決手段】燃料電池システムの制御装置１５は、燃料電池システム１の停止運転をする際に、温度センサ３６によって検出した温度に基づいて、改質水ポンプ１１ｂ１によって蒸発部３２に改質水を供給するように制御する改質水供給制御部（ステップＳ１０８，Ｓ１１０）を備えている。【選択図】図２
