PROBLEM TO BE SOLVED: To improve power generation efficiency of a fuel cell stack.SOLUTION: A reforming unit for a fuel cell includes: an evaporation part for generating steam; a reforming part for reforming mixed gas of raw fuel and steam generated at the evaporation part to produce reformed gas and supplying the reformed gas to a fuel cell stack; a heat exchange part for heating up oxidant gas and supplying the heated oxidant gas to the fuel cell stack; and a combustion part for combusting the reformed gas and the oxidant gas discharged from the fuel cell stack and generating heat to be transferred to the evaporation part, the reforming part, the heat exchange part and the fuel cell stack. The evaporation part, the reforming part, and the heat exchange part are stacked, and the combustion part is disposed so as to be adjacent to the evaporation part, the reforming part, and the heat exchange part.SELECTED DRAWING: Figure 3 |
