PROBLEM TO BE SOLVED: To provide a solid oxide type fuel battery device that can efficiently perform heat-exchange by a heat-exchange unit formed in the neighborhood of the top surface of a module case while miniaturizing the device.SOLUTION: A solid oxide type fuel battery device 1 includes a module case 8, a heat insulation material 7 covering the module case 8, a reformer 120, a combustion unit 18 for combusting fuel gas which does not contribute to power generation, air passages 161a, 161b formed between the top plate 8a and side plate 8b of the module case 8 and the heat insulation material 7, and an exhaust passage 172 extending along the air passage 161a so as to sandwich the top plate 8a between the exhaust passage 172 and the air passage 161a. The reformer 120 has an opening portion 120b through which exhaust gas is passed from the lower side to the upper side. An exhaust gas guide member 130 at the upper side of the reformer 120 is provided, at the bottom surface thereof, with a convex step portion 131a projecting downwards so as to face the opening portion 120b, and the convex step portion 131a guides the exhaust gas to the exhaust passage 172.SELECTED DRAWING: Figure 9 |
