Polymer Electrolyte Fuel Cell (PEFC) system for space applications has been studying in our 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. Usually, the temperature of the cells is controlled about 60 C to make optimum operation. However, to simplify PEFC operation, it should be run under passive heat condition, that is, without temperature control. In this study, conditions of PEFC operation were assessed to operate under passive heat condition, which was achieved by the low current density. These results could realize the simple and practical PEFC system for space and another applications., 資料番号: AA0049054016, レポート番号: JAXA-SP-05-008}, title = {固体高分子形燃料電池の低電流無加湿連続運転の研究}, year = {2006} }
