Abstract
When a fuel reforming system for a fuel cell comprising an autothermal reformer wherein a partial oxidation reaction and steam reforming reaction proceeds simultaneously, is stopped, firstly, a supply valve is closed to stop supply of fuel and water for steam reforming, and a supply valve 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 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.
