PURPOSE:To reduce the pressure variation of the reforming gas supplied to a combustion battery, by providing a catalytic combustion device having the holes of combustion gas flow passages along the inner side wall of a case-shaped furnace body and embedding a vaporizer communicating with the outside in said combustion device. CONSTITUTION:When the high temp. exhaust gas from a fuel battery 1 passes a fuel supply pipe 31 and combustion air passes through a combustion air supply pipe 32 to flow in a catalytic combustion device 26, said gaseous mixture passes through a large number of holes 27. At this time, the gaseous mixture is oxidized and burnt on the inner wall surfaces of the holes 27 in the presence of the catalyst supported by the wall surfaces of the holes 27 to generate heat, and this heat is conducted through the molded body of the catalytic combustion device 26 to be transferred to the vaporizer 29 embedded in the molded body. As a result, the liquid fuel of the reforming raw material supplied to the vaporizer 29 to flow therethrough is vaporized to become raw material gas. The raw material gas is reformed to gas rich in hydrogen by a reforming device 7 to become reforming gas which is, in turn, supplied to the fuel battery 1. |
