Patent ID: 7575729

Claim:
A fuel reforming apparatus comprising: a reforming catalyst that reforms raw gas including hydrocarbonic fuel into reformed gas including hydrogen; and a honeycomb filter comprising a plurality of partitions that are made of a first material and that are structured to form: a raw material supply flow passage that causes the raw gas to flow along a first face of the plurality of partitions and that supplies the raw gas to the filter; and a processed gas flow passage that causes reformed and filtered gas to flow along a second face of the plurality of partitions, wherein: the plurality of partitions are comprised of an interstitial material including a plurality of gaps having an effective diameter from 10 to 100 μm for trapping soot that is generated in the raw gas due to the hydrocarbonic fuel, the reforming catalyst is carried by the plurality of partitions on the second face on the side of the processed gas flow passage, and the first face of the plurality of partitions on the side of the raw material supply flow passage is only coated by an inactive second material.
