Claim:
1. A fuel cell system comprising: a fuel cell that includes a stack including a plurality of cells for generating electric power through electrochemical reaction between a fuel gas and an oxidant gas; a fuel gas supply system that supplies the fuel gas from a fuel supply source to the stack; and a fuel off-gas circulation system that resupplies fuel off-gas discharged from the stack to the stack, wherein the fuel off-gas circulation system includes: a mixed fuel gas flow path formed such that a mixed fuel gas containing the fuel off-gas and the fuel gas flows along a back surface of a manifold installed in the stack; and a point of merger where the fuel off-gas and the fuel gas merge with each other to produce the mixed fuel gas, the point of merger being arranged on an outer surface side of the manifold, the outer surface being opposed to the surface at which the mixed fuel gas flow path is formed, and wherein the mixed fuel gas flow path is defined between the manifold and a terminal for extracting electric power generated by the stack, which is arranged adjacent to the manifold.
