PROBLEM TO BE SOLVED: To provide a fuel vaporizer which can respond satisfactorily to a sharp change of loading, supply original fuel gas at a required temperature to a reformer, and fulfill the needs of such a high standard as required from a fuel battery system which is applicable to a fuel battery car. SOLUTION: The fuel vaporizer 1 has a vaporizing room 11 in where original fuel FL is vaporized to the original fuel gas FG by the heat from high- temperature heating gas HG; the vaporizing room 11 contains several vaporizing unit rooms 11A, 11B, 11C, and the unit rooms are ventilatively connected in series and are respectively equipped with an injector 40 to spray the original fuel therein; and a thermoregulation room 30, in where temperature of the original fuel gas FG, which is sent from the room 11, is regulated by heat exchange with the high-temperature heating gas HG, is connected with the vaporizing room 11. |
