To provide a fuel cell system which can prevent freezing of a coolant easily and efficiently.SOLUTION: A fuel cell system according to an embodiment includes a fuel cell part and further includes: a coolant circulation system which circulates a coolant through the fuel cell part; a heat exchange system for conducting heat exchange between sea water and the coolant circulating in the coolant circulation system; and a control unit for controlling the heat exchange. The control unit heats the coolant with the heat exchange when a temperature related to the coolant circulation system is lower than or equal to a first threshold value and a temperature of the sea water used for the heat exchange in the heat exchange system is higher than or equal to a second threshold value higher than the first threshold value.SELECTED DRAWING: Figure 1 【課題】冷却水の凍結防止を容易かつ効率的に実施可能な燃料電池システムを提供する。【解決手段】実施形態の燃料電池システムは、燃料電池部を含むと共に、燃料電池部を介して冷却水が循環する冷却水循環系と、海水と冷却水循環系を循環する冷却水との間の熱交換を行うための熱交換系と、熱交換を制御するための制御部とを備える。制御部は、冷却水循環系に関する温度が第１閾値以下であって、熱交換系において熱交換のために用いる海水の温度が第１閾値よりも高い第２閾値以上である場合に、熱交換によって冷却水を加熱する。【選択図】図１
