Patent ID: 7935315

Claim:
A reformer for a fuel cell system, comprising: a plurality of reaction substrates comprising aluminum, the plurality of reaction substrates each having a channel; a catalyst layer coated on a surface of the channels; and a close contact assembly closely contacted with at least one of the reaction substrates to form a passage through which fuel flows and comes into contact with the corresponding catalyst layer and a bare surface of the close contact assembly, wherein a first reaction substrate of the plurality of reaction substrates forms a thermal source assembly adapted to generate thermal energy through an oxidation catalytic reaction of a first fuel, wherein a second reaction substrate of the plurality of reaction substrates adjoined to the first reaction substrate forms a reforming reactor adapted to generate a reformed gas containing hydrogen through a reforming catalytic reaction of a second fuel, and wherein a third reaction substrate of the plurality of reaction substrates adjoined to the second reaction substrate on a side opposite the first reaction substrate forms a first carbon monoxide reduction assembly adapted to reduce a concentration of carbon monoxide contained in the reformed gas from the reforming reactor.
