Polymer electrolyte fuel cell (PEFC) system for space applications has been studied in the group and several subsystems and operating methods were developed such as the closed gas operation subsystem, the counter flow methodology of working gases, and gas/water separation subsystem using wicking material, which enabled the simplification of the FC system under such environment. Manufactured was the 18 cell stack and assembled fuel cell system including the components mentioned above. It showed stable performance for 1,100 hours under various operational conditions. These results could realize the simple and practical PEFC system for space application., 資料番号: AA0048057010, レポート番号: JAXA-RM-04-010}, title = {再生型燃料電池の研究}, year = {2004} }
