PROBLEM TO BE SOLVED: To provide a fuel cell system capable of realizing simple and efficient supply of raw material and a combustion gas, and realizing the long life of a desulfurizer by preventing the performance drop of the desulfurizer. SOLUTION: This fuel cell system comprises a reformer 12 for reforming a raw fuel and producing a fuel gas including hydrogen, a burner 15 for combusting a combustion fuel and heating the reformer, a fuel cell 11 for generating power by using the fuel gas and an oxidant gas, a remaining fuel gas supply passage 17 connecter to a combustor from a fuel gas outlet of the fuel cell, a fuel supply passage 18 for supplying the raw fuel to the reformer, and a combustion fuel supply passage 19 branched from the fuel supply passage and connected to the combustor. |
