Disclosed is a fuel cell system composed of a combustor and a reformer as one body. The present invention relates to a fuel cell which comprises a combustion reaction part, a reforming reaction part, a water-gas shift part and a stack, and is characterized in that the combustion reaction part, the reforming reaction part, a water-gas shift part and the stack are installed in the inside of one reactor in the form of the concentric conduit; that as for the flow of the fluid, the combustion reaction part, the reforming reaction part, the water-gas shift part and the stack are formed to have a successive stream; that the combustion reaction part and the reforming reaction part are installed to be adjacent; that the water-gas shift part is installed outside the combustion reaction part and the reforming reaction part in the form of the concentric conduit to surround; and that the water-gas shift part and the stack are installed to be adjacent to put a pre-heating space for heat exchange in the middle. The fuel cell system according to the present invention has the effect of remarkably enhancing the energy efficiency by simultaneously conducting the reforming reaction, the CO water-gas shift reaction, and the combustion reaction in a single reactor, and supplying a gas mixture with a low CO content and a high H2 content to the fuel cell. |
