摘要： PROBLEM TO BE SOLVED: To inhibit decrease in reforming reaction efficiency caused by carbon deposited on a reforming catalyst. SOLUTION: In a fuel reformer 10, a liquid reformed fuel is intermittently injected into a fuel-introducing chamber 22 by an injector 20. Meanwhile, a reforming gas comprising air and steam is heated and subsequently fed to the fuel-introducing chamber 22. When the reformed fuel is injected, it is mixed with the reforming gas, vaporized by heat of the reforming gas and introduced into the reformer 24. While injection of the reformed fuel is suspended, oxidation and removal of carbon deposited on the reforming catalyst is performed by oxygen present within the reforming gas. The fuel-introducing chamber 22 has a volume smaller than the amount of the reforming gas fed while the injection of the reformed fuel is suspended. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To decrease the operation temperature of a reformer while suppressing a deterioration in catalytic activity due to deposited carbon.
SOLUTION: A period (t1) for supplying fuel and an oxidizing agent and a period (t2) for stopping the supply of the fuel are alternately set in the operation of the reformer. In the period (t2), the catalytic activity deteriorated by the poisoning due to the deposited carbon is recovered even in a low temperature operation to improve the average value of conversion rate to hydrogen from the fuel by increasing the partial pressure of the oxidizing agent to oxidize and remove the deposition carbon. Instead of the increase in oxygen partial pressure, various operation such as the heating of the reformer in the period (t2) for removing the deposited carbon can be applied.
