A fuel reforming apparatus includes an oxidation reaction unit in which an oxidation catalyst is formed, a reforming reaction unit in which a reforming catalyst is formed, and an ignition unit for igniting a hydrocarbon-containing fuel and an oxidant and preheating the oxidation catalyst in an early driving stage. The oxidation reaction unit has a first section and a second section respectively formed opposite to each other with the oxidation catalyst interposed therebetween and forms a stream of the fuel and the oxidant flowing to the second section through the oxidation catalyst from the first section, the ignition unit being located in the second section.

An auto ignition type autothermal reformer (ATR) performs reproducible ignition using a catalyst that performs ignition without a separate ignition unit, such as an igniter or heating wire, and a fuel cell system having the ATR. The ATR includes a reaction container having a first opening through which a fuel is introduced into the reaction container and a second opening through which a reformate is discharged from the reaction container, the fuel having a mixture of an aqueous primary fuel solution and hydrogen peroxide; a first catalyst disposed adjacent to the first opening in the reaction container, the first catalyst being a granular catalyst; a second catalyst disposed at the rear portion of the first catalyst to promote an autothermal reforming reaction; and a third catalyst disposed at the rear portion of the second catalyst to promote an oxidation reaction.

A fuel reforming apparatus including reaction substrates is provided. The reaction substrates of the present invention is made of stainless steel, nickel steel, or chromium steel. Each of the reaction substrates has a channel formed on the surface of the reaction substrate. Reactant for oxidation reaction or for fuel reforming reaction flow through the channel. A catalyst containing layer is formed on the surface of the channel by directly oxidizing the surface of the channel. Therefore, the catalyst containing layer is formed with oxidized steel. A catalyst layer is formed on the catalyst containing layer. A pair of substrates can be laminated to make one substrate a thermal source unit and another a reforming reaction unit.
