抄録

A load demand following method has been proposed for polymer electrolyte fuel cell with reformer, which purifies hydrogen from reformed gas by using metal hydride. To investigate the basic performance, an exper-imental apparatus was fabricated, and absorption and release experiments of hydrogen from mimic reformed gas were carried out with LaNi metal hydride. In the results, neither poisoning nor deterioration of absorption property due to CO₂ and H₂O was verified, which are the main impurities of the steam reforming process. And approximately 100% purified hydrogen was obtained in the release process. Even if the utilization factor of the material was used over 90%, the recovery rate higher than 90% was certainly secured under a lower flow rate control condition. Therefore, satisfactory practical use performance has been demonstrated by the experiment. Also an appropriate system concept has been considered for the hydrogen release process with energy-saving, which effectively uses heat sources, such as low concentration hydrogen leak gas, heat radiation in the absorption process, and waste heat from the fuel cell system.
