@techreport{oai:jaxa.repo.nii.ac.jp:00006040, author = {曽根, 理嗣 and Sone, Yoshitsugu}, month = {Nov}, note = {Japan Aerospace Exploration Agency (JAXA) is now developing polymer electrolyte fuel cell (PEFC) systems that can be applied to the high altitude balloon, transfer vehicle, and space craft. We designed the fuel cell system for low pressure environment where the working gases were supplied by the counter-flow method and the temperature of the system was passively controlled by the heat generated from the fuel cell stack. We assembled the system and are testing its performance under the thermal vacuum conditions. Furthermore, we started the development of a fuel cell system which can be operated by the propellants for spacecraft. We tried to operate the fuel cell using Hydrazine and Nitrogen Tetra Oxide. Through our measurements, stable generation of electricity was observed using PEFC. We also tried to measure the performance of the PEFC using the propellants with additives in order to decrease the melting point of the propellants., 資料番号: AA0049500056, レポート番号: JAXA-SP-06-006}, title = {航空宇宙用燃料電池に係る研究の新しい展開}, year = {2006} }
