PROBLEM TO BE SOLVED: To provide an apparatus with improved reforming efficiency and reduction in size by collecting soot in a raw gas and removing it. SOLUTION: In a honeycomb filter 32 made of a porous material with multiple apertures, a raw gas supply flow pass 40 is formed by closing every other cells with plugs 41 at a down stream end. A filtrated gas flow passage 42 is also formed by closing the balance of cells with plugs 43 at an upper stream end. Reforming catalyst is retained on a surface of a separating wall 34 on a side of the filtrated gas flow pass 42. When the raw gas containing hydrocarbon type fuels is supplied into a reformer 30 and filtered in the honeycomb filter 32, soot 12 in the raw gas is collected in apertures and on a surface of the separating wall 34. The hydrocarbon type fuels are then reformed through the reforming catalyst to become a reformed gas containing hydrogen and carbon monoxide. By increasing a certain amount of air supplied through a blower 26 at a set time interval, the soot 12 collected at the separating wall 34 is burned and removed. |
