ABSTRACT:
The present invention provides a solid oxide fuel cell system comprising a stack including a layer of a number of cell units and separators alternated with each other, and characterized in that a set of cell units are placed on one surface between the separators, wherein each cell unit in the set is separately placed on the surface crossing at right angles to the layered direction, and wherein internal manifolds for fuel gas supply/exhaust and internal manifolds for oxidant gas supply/exhaust are formed around each cell unit, and all of them are formed through the separators.
