PROBLEM TO BE SOLVED: To provide a solid oxide type fuel cell capable of maintaining a performance of a desulfurizer in the case of storage after stopping power generation while ensuring cost reduction and energy loss reduction.SOLUTION: The solid oxide type fuel cell includes: a modifier 1 which performs water vapor modification on raw material gas to produce fuel gas; a desulfurizer 2 provided in the middle of a raw material gas supply path 7 at an upstream side of the modifier 1; an evaporator 3 that is provided in the middle of the raw material gas supply path 7 at the upstream side of the modifier and a downstream side of the desulfurizer 2, evaporates water supplied through a water supply path 20 and mixes atomized water vapor with the raw material gas supplied through the raw material gas supply path 7; and a cell stack 5 including a plurality of fuel battery cells 4 for generating power by oxidizing and reducing the fuel gas and an oxidant. In the solid oxide type fuel cell, a folded-back part K is provided which is folded back in such a manner that the middle of the raw material gas supply path 7 between the desulfurizer 2 and the evaporator 3 is projected downward, to store water. |
