This attention has enhanced their research and development. In the field of space engineering, fuel cells have been applied to spacecraft like GEMINI and other manned operations since the 1960's. Since a fuel cell produces water as a byproduct of generating electricity, it is very attractive for manned operations in a closed environment. Furthermore, the fuel cell generates energy using hydrogen and oxygen, both of which have high energy density. Due to this high potential, fuel cells are still advantageous for application to large spacecraft with short-term missions. The first practical application of the fuel cell in space was for the GEMINI project in the 1960's. The first fuel cell to travel in space was the PEFC. The membrane for the fuel cell was polystyrene, not perfluoro-membrane, and high power supply, commonly achievable today, was not realized. When the APOLLO and Space Shuttle missions started, PEFC was replaced by an alkaline fuel-cell system. Today, PEFCs are beginning to receive a considerable amount of attention again for aerospace applications. One example is the Stratospheric Platform Project. A lightweight, long-duration generating system is now required to maintain the altitude and position of a balloon or an airship in the stratosphere. For space applications, a variety of missions are proposed that will need the fuel-cell system. One example is a transfer vehicle in low-Earth orbit. The demonstration using the balloon and launch vehicles will enhance the development of fuel cell system, and realize fuel cell applications to the above missions. Furthermore, fuel cell system using propellant will save the weight of the satellite for planetary missions. It will also prevent the risk of making debris due to the malfunction of satellites. Thus, the fuel cell system will become an important basic technology commonly required for future spacecraft.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047275013","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構 宇宙科学研究本部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Institute of Space and Astronautical Science"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"曽根, 理嗣"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sone, Yoshitsugu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"燃料電池","subitem_subject_scheme":"Other"},{"subitem_subject":"研究開発","subitem_subject_scheme":"Other"},{"subitem_subject":"電気自動車","subitem_subject_scheme":"Other"},{"subitem_subject":"固体電解質燃料電池","subitem_subject_scheme":"Other"},{"subitem_subject":"フッ素化ポリマー","subitem_subject_scheme":"Other"},{"subitem_subject":"イオン交換樹脂","subitem_subject_scheme":"Other"},{"subitem_subject":"有人軌道実験室","subitem_subject_scheme":"Other"},{"subitem_subject":"成層圏プラットフォーム","subitem_subject_scheme":"Other"},{"subitem_subject":"fuel cell","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"research and development","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"electric automobile","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"polymer electrolyte fuel cell","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fluoropolymer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ion exchange resin","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"manned orbital laboratory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stratospheric platform","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"宇宙用燃料電池の技術背景と今後の展開","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"宇宙用燃料電池の技術背景と今後の展開"}]},"item_type_id":"5","owner":"1","path":["1578","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"8129","relation_version_is_last":true,"title":["宇宙用燃料電池の技術背景と今後の展開"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:28:00.749236+00:00"}
