Provided is a fuel processing device including: a combustion unit equipped with a heat source; a desulfurization unit for extracting a sulfur component from the source gas; a reforming unit for generating, from the desulfurized source gas, a hydrogen-containing gas having hydrogen as a main component thereof; and a low-temperature conversion unit equipped with an exothermic catalyst for reducing the impurity concentration in the hydrogen-containing gas. The reforming unit and the desulfurization unit are configured so as to surround the combustion unit, and are disposed concentrically in the given order facing outwards from the combustion unit. The present invention further includes a preheating passage which is connected to the desulfurization unit, and which is provided to a bottom part of the combustion unit via a heat insulation material, such that the source gas is preheated by heat from the combustion unit. |
