Patent ID: 8273141

Claim:
A manufacturing method of a fuel reforming apparatus, comprising steps of: preparing a first substrate made of a first metal; forming a first channel on an upper surface of the first substrate; oxidizing an inner surface of the first channel to form an oxidized inner surface, the oxidized inner surface of the first channel being a first catalyst containing layer, the first catalyst containing layer including one selected from the group consisting of Fe 2 O 3 , Fe 3 O 4 and FeO; forming an oxidation catalyst layer on the oxidized inner surface of the first channel to promote an oxidation reaction between a fuel and air, the oxidation catalyst layer completely covering the first catalyst containing layer not to promote the oxidation reaction in the first catalyst containing layer; preparing a second substrate made of a second metal; forming a second channel on an upper surface of the second substrate; oxidizing an inner surface of the second channel, the oxidized inner surface of the second channel being a second catalyst containing layer; forming a reforming catalyst layer on the oxidized inner surface of the second channel to promote a reforming reaction; placing the second substrate on the upper surface of the first substrate in a manner that a lower surface of the second substrate contacts the upper surface of the first substrate; and placing a cover plate on the upper surface of the second substrate.
