Abstract:
1. A fuel reformer device in which a steam reforming reaction, which is endothermic and produces hydrogen from a crude fuel and steam, and an oxidation reaction, which is exothermic and oxidizes the crude fuel, proceed and heat generated by the oxidation reaction is utilized for a progress of the steam reforming reaction, said fuel reformer device comprising: a catalytic section that includes a catalyst for accelerating the steam reforming reaction and the oxidation reaction; a crude fuel gas supply unit that flows a supply of a crude fuel gas containing the crude fuel, steam, and oxygen into said catalytic section; a gaseous fuel output unit that causes a hydrogen rich gaseous fuel, which is produced through the steam reforming reaction and the oxidation reaction proceeding in said catalytic section, to be output from said catalytic section; and a gas flow velocity regulation unit that regulates a flow velocity of the crude fuel gas to be higher in an area on a side receiving the supply of the crude fuel gas than in an area on a side outputting the gaseous fuel in said catalytic section, so as to enable the heat generated by the oxidation reaction proceeding in the area on the side receiving the supply of the crude fuel gas to be sufficiently transmitted to the area on the side outputting the gaseous fuel.
