HYDROGEN SUPPLY APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent gas leakage generated on a seal part in a hydrogen supply apparatus provided with a rotary heat exchanger. SOLUTION: A hydrogen supply apparatus has a low temperature fluid passage A, a high temperature fluid passage B provided with combustion gas supply part 70 for generating a combustion gas and a rotary heat storage body 21 moving alternately to the low temperature fluid passage A and the high temperature fluid passage B and is provided with the heat exchanger 20 for transferring the heat of combustion to the raw material to be reformed. The low temperature fluid passage A and the high temperature fluid passage B are communicated with each other through a fuel cell 60 and a gas compressor 51 is provided at the upstream side of the fuel cell 60. Pressure control valves 14 and 83 are provided respectively at the down stream side of the heat exchanger 20 in the high temperature fluid passage B and the upstream side of the heat exchanger 20 in the low temperature fluid passage A. The opening of the pressure control valves 14 and 83 is controlled so that the pressure of the high temperature fluid pressure Pb is almost equal to or higher than the low temperature fluid pressure Pa.
