Abstract: When a fuel reforming system for a fuel cell comprising an autothermal reformer 1 wherein a partial oxidation reaction and steam reforming reaction proceeds simultaneously, is stopped, firstly, a supply valve 6 is closed to stop supply of fuel and water for steam reforming, and a supply valve 7 is closed after a predetermined time has elapsed to stop supply of air. In this way, the partial oxidation reaction which is an exothermic reaction is continued temporarily and the catalyst layer temperature of the reformer 1 is raised, so the catalyst layer temperature can be maintained high until the system restarts, and the time required for restarting the system can be shortened.

Abstract: A fuel reforming apparatus quickly heats the temperature of a catalyst to an activation temperature to shorten a startup time. The apparatus supplies a hydrocarbon fuel and an oxidizer upstream from a second catalyst (2), and steam upstream from a first catalyst (1). The second catalyst starts a rapid oxidation reaction to generate a high-temperature gas which heats the first catalyst. When the apparatus changes a startup operation or an accelerating operation to a steady operation after a predetermined period, the apparatus supplies the hydrocarbon fuel and steam upstream from the second catalyst, and the oxidizer upstream from the first catalyst. As a result, the second catalyst starts a steam reforming reaction to absorb heat from the second catalyst. And the second catalyst rapidly cools to stop reactions and pass the hydrocarbon fuel and steam with out reactions. Then, a hydrogen-rich reformed gas is generated from the passed hydrocarbon fuel and steam.
