In the H2/O2 fuel cell tests at 60 °C, by optimizing dew points, the sterically hindered imidazolium containing StIm-based AEMs exhibited the highest power density (710 mW/cm2), which is one of the highest performances of imidazolium-type AEMs to date. Furthermore, it exhibited long-term durability in H2/O2 fuel cell at 60 °C, maintaining 0.52 V (56%) of initial voltage after 670 h of life time test, which is better than that of the standard BTMA-based AEM. The chemical characterization in post-durability characterization revealed that negligible degradation of conducting imidazolium groups in the 2MVIm-, 4VIm-, and StIm-based AEMs was observed. For the first time, the hydration level and DFT-based molecular calculations (LUMO energy) showed an acceptable correlation with the experimental in-situ durability results.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.memsci.2020.118844","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S0376738820314198","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0376-7388","subitem_source_identifier_type":"ISSN"}]},"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":"Mahmoud Ahmed Mohamed, Ahmed"}],"nameIdentifiers":[{"nameIdentifier":"1009724","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kimio, Yoshimura"}],"nameIdentifiers":[{"nameIdentifier":"1009725","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasunari, Maekawa"}],"nameIdentifiers":[{"nameIdentifier":"1009726","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mahmoud Ahmed Mohamed, Ahmed","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1009727","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kimio, Yoshimura","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1009728","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasunari, Maekawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1009729","nameIdentifierScheme":"WEKO"}]}]},"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":"Alkaline fuel cells consisting of imidazolium-based graft-type anion exchange membranes: Optimization of fuel cell conditions to achieve high performance and durability","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Alkaline fuel cells consisting of imidazolium-based graft-type anion exchange membranes: Optimization of fuel cell conditions to achieve high performance and durability"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-04-06"},"publish_date":"2021-04-06","publish_status":"0","recid":"82638","relation_version_is_last":true,"title":["Alkaline fuel cells consisting of imidazolium-based graft-type anion exchange membranes: Optimization of fuel cell conditions to achieve high performance and durability"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:06:39.131005+00:00"}
