To provide a fuel cell system in which freezing of a valve device can be suppressed and can be quickly thawed even when the valve device is frozen, with simple configuration.SOLUTION: A fuel cell system 10 comprises a gas-liquid separator 60 that separates moisture from a fuel off-gas discharged from a fuel cell stack 12, and a valve device 72 provided in a discharge channel 70 for discharging water separated by the gas-liquid separator 60. The valve device 72 has a fluid introduction part 92 that guides a fluid including at least water in the gas-liquid separator 60 to a valve body 90, and a heating device 116 is disposed in an inner hole 92a of the fluid introduction part 92.SELECTED DRAWING: Figure 2 【課題】簡易な構成により、弁装置の凍結を効果的に抑えることができ、且つ弁装置が凍結した場合であっても速やかに解凍することができる燃料電池システムを提供する。【解決手段】燃料電池システム１０は、燃料電池スタック１２から排出された燃料オフガスから水分を分離する気液分離器６０と、気液分離器６０で分離された水を排出するための排出流路７０に設けられた弁装置７２とを備える。弁装置７２は、気液分離器６０内の少なくとも水を含む流体を弁本体９０に導く流体導入部９２を有し、流体導入部９２の内孔９２ａには、加熱装置１１６が配設されている。【選択図】図２
