PROBLEM TO BE SOLVED: To prevent heat radiation from a reforming device and also to lower exhausted gas temperature from an exterior case. SOLUTION: A reformer, a CO transformer, and a CO remover are stored in a metal box 1, and a heat insulation material 10 is attached on an inner wall of the box 1. A duct 12 is arranged on the box 1, and heat exchangers 13a, 13b are provided so as to pinch the duct 12 like a sandwich, and connected and integrated by a connecting pipe 8. Burning exhaust gas from a reformer burner and a PG burner, and non-reacted oxygen gas from a fuel cell are introduced in the duct 12 and cooled down. Three routes R1, R2 and R3 are provided in the duct 12 separated by partition boards 12a and 12b, and the burning exhaust gas and non-reacted oxygen gas are introduced separately in the routes, and are made to pass through them. |
