Reformer for fuel cell system, fabrication method therefor, and fuel cell system comprising the same

A method for fabricating a reformer for a fuel cell system, comprising:

• forming a flow channel in a reaction substrate body, the reaction substrate body comprising a material selected from the group consisting of aluminum, and aluminum-containing alloys selected from the group consisting of Al—Mn, Al—Mg, Al—Cu—Mg, Al—Mg—Si, Al—Si, and Al—Cu—Si, and combinations thereof;
• forming micropores within the flow channel by anodizing a surface of the flow channel;
• forming a catalyst layer within the flow channel;
• and
• arranging a plurality of reaction substrates in a stack.

A fuel cell system, comprising:

• a fuel supplying unit for supplying mixed fuel;
• a reforming unit comprising:
• a reformer comprising a plurality of reaction substrates each of which comprises a reaction substrate body having at least one flow channel and micropores on a surface of the at least one flow channel, the reaction substrate body comprising a material selected from the group consisting of aluminum, aluminum-containing alloys selected from the group consisting of Al—Mn, Al—Mg, Al—Cu—Mg, Al—Mg—Si, Al—Si, Al—Cu—SiU, and combinations thereof;
• and
• a catalyst layer within the micropores of the at least one flow channel of each reaction substrate body;
• a stack for generating electric energy by an electrochemical reaction between hydrogen gas supplied from the reforming unit and oxidant;
• and
• an oxidant supplying unit for supplying oxidant to the stack and the reforming unit.
