A fuel reforming apparatus includes a reforming reaction section in which a reforming catalyst is disposed, and a reformed fuel distribution chamber. A fuel air mixture of a hydrocarbon fuel and air is reformed in the reforming reaction section. The reformed fuel is supplied from the reformed fuel distribution chamber to chambers of the engine. The adsorbent member is disposed between the reforming reaction section and the reformed fuel distribution chamber. The adsorbent member captures a non-reformed fuel.

What is claimed is: 1. A fuel reforming apparatus for reforming a fuel air mixture of a fuel and air, comprising: a reforming catalyst for reforming said fuel air mixture; a reformed fuel supply section for supplying a reformed fuel produced by said reforming catalyst to a predetermined object; capturing means for capturing a non-reformed fuel, said capturing means being disposed between said reforming catalyst and said reformed fuel supply section; and cooling means for cooling said reformed fuel between said reforming catalyst and said capturing means, the cooling means being a heat exchanging means having a reformed fuel passage for leading said reformed fuel from said reforming catalyst to said reformed fuel supply section and a heating medium passage for circulating a heating medium to exchange heat between said heating medium and said reformed fuel flowing through said reformed fuel passage; and the capturing means being an adsorbent material for adsorbing said non-reformed fuel in said reformed fuel passage of said heat exchanging means. 2. The fuel reforming apparatus of claim 1, wherein said capturing means is disposed in an outer region of a passage connecting said reforming catalyst and said reformed fuel supply section. 3. The fuel reforming apparatus of claim 1, further comprising: a first passage connecting said reforming catalyst and said reformed fuel supply section; a second passage bypassing part of said first passage and connecting said reforming catalyst and said reformed fuel supply section; and opening/closing means for opening and closing said first passage, wherein said capturing means is disposed in said second passage and includes an adsorbent material for adsorbing said non-reformed fuel. 4. The fuel reforming apparatus of claim 3, wherein said second passage connecting a portion of said first passage upstream of said opening/closing means and a portion of said first passage downstream of said opening/closing means. 5. The fuel reforming apparatus of claim 4, wherein said second passage surrounds said first passage. 6. The fuel reforming apparatus of claim 3, wherein said opening/closing means is closed from a start of a fuel reforming operation in said reforming catalyst until a predetermined period has lapsed, or until said adsorbent material has reached a predetermined temperature. 7. The fuel reforming apparatus of claim 1, further comprising non-reformed fuel recovering means for recovering said non-reformed fuel captured by said capturing means and supplying said non-reformed fuel to said reforming catalyst again. 8. The fuel reforming apparatus of claim 7, wherein said non-reformed fuel recovering means comprises: negative pressure generating means for generating a negative pressure by using a flow of air supplied to said reforming catalyst; and a passage connecting said negative pressure generating means and said capturing means. 9. The fuel reforming apparatus of claim 1, wherein said predetermined object is a combustion chamber of an internal combustion engine, and wherein said heating medium is part of air supplied to said combustion chamber. 10. A method of reforming a fuel air mixture of a fuel and air with a reforming catalyst, comprising: providing a reformed fuel through a reformed fuel passage between the reforming catalyst and a reformed fuel supply section, for supplying a reformed fuel produced by the reforming catalyst to a predetermined object; capturing a non-reformed fuel within said reformed fuel passage with an adsorbent material; and cooling said reformed fuel by a heat exchanging means having said reformed fuel passage and a heating medium passage for circulating a heating medium to exchange heat between said heating medium and said reformed fuel flowing through said reformed fuel passage. 11. The method of claim 10, further comprising: cooling said reformed fuel between said reforming catalyst and a capturing means. 12. The method of claim 10, further comprising: recovering said non-reformed fuel captured by said adsorbent material and supplying said non-reformed fuel to said reforming catalyst again.
