A new methane-steam reforming system for a fuel cell has been developed on the basis of the effective energy conversion method between flowing gas enthalpy and thermal radiation. The basic concept consists of a porous medium (heating side) and a porous catalyst (cooling side) which are separated by a solid wall. A combustion gas, which is used for heating the system, flows in the porous medium toward the receding direction from the separating wall, and the flowing gas enthalpy is effectively converted into radiant energy emitted in the upward direction. Conversely, a methane-steam mixture is supplied to the cooling side, and the radiant energy is effectively converted into endothermic reaction heat for the production of hydrogen in the porous catalyst. Consequently, the experimental results show that the compactness of the proposed reforming system can be improved, compared with conventional tubular reformers, to a considerable extent.
