PROBLEM TO BE SOLVED: To provide an improved fuel cell system.SOLUTION: A fuel cell system 2 comprises: a fuel cell 3; a fuel tank 22 for storing liquid fuel; a fuel supply line 30 for supplying the liquid fuel from the fuel tank 22 to the fuel cell 3; a fuel discharge line 31 for discharging discharge liquid from the fuel cell 3; a reflux line 32 for delivering the discharge liquid from the fuel discharge line 31 to the fuel supply line 30; a concentration adjustment tank 47 for adjusting the concentration of the liquid fuel, the concentration adjustment tank 47 being interposed on the fuel supply line 30 and connected to the reflux line 32; and a water separator 45 for separating water from the liquid fuel in the concentration adjustment tank 47. The concentration adjustment tank 47 comprises: a discharge liquid inlet 56 for supplying the discharge liquid to the water separator 45; and a fuel outlet 55 for discharging the liquid fuel from the concentration adjustment tank 47. The water separator 45 is formed such that it intersects with a virtual line segment L connecting the discharge liquid inlet 56 to the fuel outlet 55.SELECTED DRAWING: Figure 3 |
