PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell module to be applied to a practical machine of a solid electrolyte fuel cell. SOLUTION: This module is provided with a fuel cell stack 12 where a solid electrolyte fuel cell is connected in series to a power generation chamber 11, a fuel supply chamber 13 to supply natural gas as fuel 22 and steam to a fuel cell of the power generation chamber 11, a fuel exhaust chamber 14 to discharge fuel exhaust gas and unconverted gas generated by fuel cell reaction to an external part as exhaust fuel 25 and a heat exchanger 17 to exchange heat between air 24 supplied to the power generation chamber 11 and exhaust air 26, and is constituted by surrounding these by a heat insulating material 19. In this case, a prereformer 31 having a steam reforming catalyst is arranged in the fuel supply chamber 13, and reforming reaction of natural gas of the previous fuel 22 and steam supplied to the fuel cell stack 12 is performed, and exhaust heat at power generation time is absorbed by heat absorbing reaction at that time. |
