To provide a fuel cell system that can prevent water from accumulating in a hydrogen circulation pump.SOLUTION: When the flow rate per unit time of a hydrogen circulation pump 60 in a state in which a fuel cell 10 operates is a first flow rate, the hydrogen circulation pump 60 operates at a second flow rate which is a flow rate smaller than a first flow rate per unit time of the hydrogen circulation pump 60 in the state in which the fuel cell 10 is stopped.SELECTED DRAWING: Figure 1 【課題】水素循環ポンプに水が溜まることを抑制できる燃料電池システムを提供すること。【解決手段】燃料電池１０が稼働している状態の水素循環ポンプ６０の単位時間あたりの流量を第１流量とすると、燃料電池１０を停止させた状態において、水素循環ポンプ６０は、水素循環ポンプ６０の単位時間あたりの流量が第１流量よりも小さい流量である第２流量で稼働する。【選択図】図１
