PROBLEM TO BE SOLVED: To provide a solid oxide type fuel battery system that can use, as fuel, carbon mono-oxide contained in exhausted fuel gas from which hydrogen is separated while hydrogen is separated from the exhaust fuel gas and effectively used.SOLUTION: An SOFC module 201 includes a cell stack 101 for reacting hydrogen and carbon mono-oxide contained in fuel gas supplied to a fuel electrode side with oxidant gas supplied to an air electrode side, a reforming tube 102 which is disposed adjacent to the cell stack 101 and reforms hydrocarbon-based gas to produce fuel gas containing hydrogen and carbon mono-oxide, a hydrogen separator 270 for separating hydrogen contained in fuel gas G3 exhausted from the reforming tube 102, and exhausting first exhaust fuel gas G1 containing carbon mono-oxide, and a second exhaust fuel gas circulation system 241 for supplying the first exhaust fuel gas G1 exhausted from a hydrogen separator 270 to a fuel electrode of the cell stack 101.SELECTED DRAWING: Figure 7 |
