PROBLEM TO BE SOLVED: To provide a fuel cell system that can sufficiently vaporize reforming water at low temperature during system startup.SOLUTION: A fuel cell system 10 comprises a first unit 16 connected to a reforming material feed path, a connection part 18 connected at a downstream side of the first unit, a second unit 20 connected at a downstream side of the connection part, a cell stack 22, and a combustion part 24 provided at an upper side of the cell stack 22 for combusting hydrogen-containing gas using oxygen-containing gas. The first unit 16 has a first vaporizer 28 capable of vaporizing reforming water W1 with heat of exhaust gas G3. The second unit 20 is arranged at an upper side of the combustion part and integrally has a second vaporizer 30 capable of vaporizing reforming water that has passed without being vaporized at the first unit with combustion heat of the combustion part and a reforming device 32 provided at a downstream side of the second vaporizer. The first unit 16 is arranged at a downstream side of the second unit 20 along an exhaust gas path. |
