<P>PROBLEM TO BE SOLVED: To provide an operating method for such a reformer used in combination with a fuel cell as is contrived to achieve high efficiently, to down-size, and to control the reforming temperature. <P>SOLUTION: The operating method for the reformer which is used in combination with a fuel cell and which manufactures hydrogen by the steam reforming of a hydrocarbon-based fuel containing no oxygen atom in the molecular structure, is characterized in that the whole quantity or large portion of the heat required at the reformer is covered with the combustion heat of the off-gas out of the fuel cell by letting a reforming conversion ratio of the hydrocarbon- based fuel at the reformer to less than 90%. <P>COPYRIGHT: (C)2003,JPO |
