A fuel reforming device generates reformate gas containing a large amount of hydrogen by reforming a mixture of a hydrocarbon fuel and air, and supplies the reformate gas to a fuel cell stack ( 14 ). The fuel reforming device comprises a fuel injector ( 1 ) injecting the hydrocarbon fuel into a fuel mixing chamber ( 24 ), first and second air distribution valves ( 10, 11 ) supplying air to the fuel mixing chamber ( 24 ), and a reformer ( 5 ) which generates reformate gas by making the air-fuel mixture supplied from the fuel mixing chamber ( 24 ) react in the presence of a reforming catalyst. The reformer ( 5 ) is also provided with an oxidation catalyst. When the fuel reforming device starts operating, a large amount of air is supplied from the first and second air distribution valves ( 10, 11 ) to the fuel mixing chamber ( 24 ), and the oxidation catalyst in the reformer ( 5 ) promotes oxidation of the air-fuel mixture to warm up the reformer ( 5 ).
