<P>PROBLEM TO BE SOLVED: To provide a heat exchange type reformer which is good in the heat exchange efficiency between a heating part and a reforming part. <P>SOLUTION: In the heat exchange type reformer 10, a reforming flow passage 18, on which a reforming catalyst for a reforming reaction is supported, and a combustion flow passage 20, on which an oxidation catalyst for combustion is supported, are adjacent to each other through a plate part 52. In the reforming flow passage 18 for forming a hydrogen-containing reformed gas from a supplied reforming raw material and the combustion flow passage 20 for supplying heat generated by the catalytic combustion of a supplied fuel to the reforming flow passage 18, the gas flow directions are both set to be in the direction as indicated by the arrow F, and thereby, a parallel-flow type heat exchanger is constituted in heat exchange flow passages 58A, 64A. At the upstream in the gas flow direction of the heat exchange flow passages 58A, 64A, a reforming gas guide flow passage 58B for guiding the reforming raw material to the heat exchange flow passage 58A along a predetermined direction and a mixed gas guide flow passage 64B for guiding the fuel to the heat exchange flow passage 64A along the direction crossing with the gas flow direction in the reforming gas guide flow passage 58B are provided. <P>COPYRIGHT: (C)2008,JPO&INPIT |
