An indirect inside reforming SOFC system that enables elimination of the use of hydrogen storage equipment for anode protection at start-up, etc. There is provided an indirect inside reforming solid oxide fuel cell comprising a first reformer for producing a reformate gas from a hydrocarbon fuel with the use of steam reforming reaction; a solid oxide fuel cell for power generation from the reformate gas obtained by the first reformer; and a container for housing both of the first reformer and the solid oxide fuel cell, wherein the first reformer is disposed at a position receiving heat radiation from the solid oxide fuel cell. Further, there is provided an indirect inside reforming solid oxide fuel cell system comprising the indirect inside reforming solid oxide fuel cell and further comprising a second reformer for reforming a hydrocarbon fuel to thereby produce a reformate gas, disposed outside the container; and a line leading the reformate gas obtained by the second reformer from the second reformer to an anode of the solid oxide fuel cell.
