Summary:To provide a fuel cell system which can control the temperature of liquid fuel such that its temperature range may be suitable for an electrode reaction in an electrode structure.SOLUTION: A fuel cell system comprises a heater 50 which heats liquid fuel in a fuel supply passage 11 of an anode-side separator 10. Along the fuel supply passage 11, the heater 50 is divided into a first heater 51 (a first high-temperature heater 51a and a first low-temperature heater 51b), a second heater 52 (a second high-temperature heater 52a and a second low-temperature heater 52b), and a third heater 53. In the first heater 51, the second heater 52, and the third heater 53, the amount of heat input is controlled such that the liquid fuel temperature on a fuel supply port 12 side of the liquid fuel into the fuel supply passage 11 may be suitable for an electrode reaction before the heaters heat the liquid fuel flowing through the fuel supply passage 11.SELECTED DRAWING: Figure 9 【課題】電極構造体における電極反応に適した温度域となるように、液体燃料の温度を制御することができる燃料電池システムを提供すること。【解決手段】燃料電池システムは、アノード側セパレータ10の燃料供給流路11において液体燃料を加熱するヒータ50を備える。ヒータ50は、燃料供給流路11に沿って、第一ヒータ51(第一高温ヒータ51a及び第一低温ヒータ51b)と、第二ヒータ52(第二高温ヒータ52a及び第二低温ヒータ52b)と、第三ヒータ53とに分割される。第一ヒータ51、第二ヒータ52及び第三ヒータ53は、燃料供給流路11に対する液体燃料の燃料供給口12側における液体燃料の温度が電極反応に適する温度になるように入熱量が制御され、燃料供給流路11を流れる液体燃料を加熱する。【選択図】図9
