PURPOSE:To realize a short starting time by reducing the temperature up time of a fuel reforming system without increasing the thermal fatigue of a reformer and a catalyst layer. CONSTITUTION:In the temperature up period of a fuel reforming system, the internal pressure is maintained higher than the reforming pressure scope, and when the operation is moved from the temperature up period to the reforming operation, the opening of a vent valve is regulated to make the internal pressure lower than the reforming pressure scope. |
