Therefore, to achieve suitable control, it is necessary to clarify the mass transfer characteristics within a GDL by high precision measurement of oxygen diffusivity. We have previously proposed that measurement of the effective oxygen diffusivity in a GDL containing moisture can be achieved using a galvanic cell oxygen absorber and demonstrated this to be an effective technique for the measurement of microporous media. However, the diffusion resistance of a single dry GDL is low, so that the margin of error in the oxygen diffusivity measurement is high. In this study, high precision measurement of the oxygen diffusivity in a GDL was developed further by analysis of the major error factors and modification of the measurement apparatus configuration. The results indicate a reduction in the maximum measurement error from 50% to 20% for a dry GDL with minimal diffusion resistance.","subitem_description_type":"Abstract"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"コレサワ, リョウ"}]},{"nameIdentifiers":[{}],"names":[{"name":"ウタカ, ヨシオ"}]}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{}]}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00680396","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00179310","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Engineering, Yokohama National University"},{"subitem_text_value":"Faculty of Engineering, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Koresawa, Ryo"}],"nameIdentifiers":[{"nameIdentifier":"19298","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Utaka, Yoshio"}],"nameIdentifiers":[{"nameIdentifier":"19299","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-09-16"}],"displaytype":"detail","filename":"140502_revised_manuscripts_and_figures_投稿版.pdf","filesize":[{"value":"975.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"140502_revised_manuscripts_and_figures_投稿版.pdf","url":"https://ynu.repo.nii.ac.jp/record/4182/files/140502_revised_manuscripts_and_figures_投稿版.pdf"},"version_id":"40768630-6f85-4517-8a40-9aa368cc9a2a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"effective oxygen diffusivity","subitem_subject_scheme":"Other"},{"subitem_subject":"galvanic cell oxygen absorber","subitem_subject_scheme":"Other"},{"subitem_subject":"gas diffusion layer","subitem_subject_scheme":"Other"},{"subitem_subject":"polymer electrolyte fuel cell","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Precise measurement of effective oxygen diffusivity for microporous media containing moisture by review of galvanic cell oxygen absorber configuration","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Precise measurement of effective oxygen diffusivity for microporous media containing moisture by review of galvanic cell oxygen absorber configuration"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-09"},"publish_date":"2015-03-09","publish_status":"0","recid":"4182","relation_version_is_last":true,"title":["Precise measurement of effective oxygen diffusivity for microporous media containing moisture by review of galvanic cell oxygen absorber configuration"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T21:30:58.949146+00:00"}
