Abstract: 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.

With this configuration, the fuel reformer and the CO remover can be directly heated by a heat source. Then, when the temperature of the CO remover reaches a catalyst activation temperature, the heat source can be moved to directly heat only the fuel reformer, thereby enhancing a reforming effect and a power generation efficiency of the fuel reforming system.

Abstract: A plate-type heat exchanger for use in a fuel cell system that has a fuel cell stack and a reformer is provided. The heat exchanger includes a substrate and a pair of cover plates. The substrate has a first face and a second face opposite to the first face. The substrate is disposed between the cover plates, and combined with the cover plates to form a first passageway and a second passageway.

The second passageway is formed in the second face, and circulates water supplied from the water supply source. The water is supplied to the reformer after the circulation. The heat exchanger of the present invention improves performance and efficiency of a fuel cell system.

Abstract: The present invention creates oxide and air apertures in material systems, such as InP, that do not usually accommodate epitaxial incorporation of highly oxidizing materials, such as AlAs, of sufficient thickness to adequately provide optical as well as current aperturing. A composite structure of relatively slowly oxidizing layer or layers (e.g. AlInAs on InP) with a faster-oxidizing layer or layers (e.g. AlAs on InP) can be used to produce oxide and air apertures of various shapes and sizes, and to also increase the oxidation rate.
