(JP10236802-A)      A fuel reforming apparatus comprises a heating portion (1) for the liquid feed comprising water and alcohol or hydrocarbon; a portion (2) for evaporating the heated liquid feed to generate feed gases; a portion (3) for superheating the feed gases from an evaporation to a reforming temperature; a reforming portion (4) for generating H2 rich reformed gases from the superheated feed gases by reforming catalysts; a catalytic combustion portion (6a,b) for supplying reforming heat to the reforming portion and evaporation heat to the evaporation portion and the steam superheating portion by combustion of the catalysts; a shift reaction portion (4a) for reducing CO in the gases generated by the reforming portion; a CO oxidation portion (5) for reducing the CO contained in the reformed gases emerging from the shift portion by catalytic oxidation; and a heat recovery portion (7a,b) for using exhaust heat of high temperature combustion gases obtained by the combustion of the catalysts as h eat sources for the steam superheating portion and the evaporation portion. The elements are formed into flat plates of light alloy, having a manifold for performing intake and exhaust and also having heat transfer fins in the interior, and integrally stacked in close proximity to one another from a high temperature side to a low temperature side in the order of (6b), (4), (3), (7b), (4a), (2), (5) and (1).    USE -   The apparatus is used for reforming fuel, e.g., for generating H2 for portable fuel cells, or for converting alcohol or hydrocarbon to hydrogen-rich reformed gases.    ADVANTAGE -   The apparatus is compact, suitable for mass production, supplies heat directly by the combustion of off-gases and sets the temperature distribution of the CO oxidation portion to the optimum.
