PROBLEM TO BE SOLVED: To keep the temperature of a reforming gas from a reformer almost constant for supplying hydrogen to a molten carbonate fuel cell system, regard less of the changes of a load. SOLUTION: An innermost pipe 8 for heat transfer control is arranged, extending coaxially in an inner pipe 2, a low-temperature reforming gas flow control valve 12 is provided at the exit of the inner pipe 2, and a high- temperature reforming gas flow control valve 11 is provided at the exit of the innermost pipe 8. A supply pipe 15 is provided, communicating with the exits of the flow control valves 11, 12 and a temperature sensor 13 is provided for measuring the temperature of the mixture reforming gas flowing in the supply pipe 15. The openings of the flow control valves 11, 12 are controlled in response to the measured temperature of the reforming gas for keeping constant the temperature of the reforming gas supplied from the reformer. |
