PEEK-Si3 and -Si5 exhibited 10%-50% higher grafting degrees (GDs) compared with those of a silica-free PEEK film. PEM-Si3 and -Si5 showed similar and slightly higher water uptakes in the lower- and higher-relative-humidity (RH) ranges compared with that of the silica-free PEMs. Under the fully humidified condition at 80 °C, PEM-Si3 exhibited the highest tensile strength (TS) (16.4 MPa), which is 1.27 and 1.64 times greater than those of the silica-free PEM and Nafion 212. The membrane electrode assembly (MEA) prepared from PEM-Si3 with an IEC of 3.30 mmol/g showed a maximum power density of 612 mW/cm2 under 30% RH, which was 7% higher than that of the silica-free PEM-based MEA. On the basis of the aforementioned results, we concluded that (1) nanosilica was introduced into both hydrophilic (ion channel) and hydrophobic (matrix PEEK) phases in the PEMs; (2) nanosilica in the hydrophilic phase exhibits greater water absorption tendency but not greater water retention character, under high- and low-RH conditions, respectively; and (3) nanosilica in the hydrophobic phase increases the mechanical properties of silica-containing PEMs. ","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ijhydene.2016.08.039","subitem_relation_type_select":"DOI"}}]},"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":"Hamada, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"479126","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukasawa, Hideyuki"}],"nameIdentifiers":[{"nameIdentifier":"479127","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasegawa, Shin"}],"nameIdentifiers":[{"nameIdentifier":"479128","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miyashita, Atsumi"}],"nameIdentifiers":[{"nameIdentifier":"479129","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maekawa, Yasunari"}],"nameIdentifiers":[{"nameIdentifier":"479130","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"長谷川 伸","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"479131","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮下 敦巳","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"479132","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"前川 康成","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"479133","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":"Graft-type polymer electrolyte membranes based on poly(ether ether ketone)/nanosilica hybrid films for fuel cell applications","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Graft-type polymer electrolyte membranes based on poly(ether ether ketone)/nanosilica hybrid films for fuel cell applications"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-20"},"publish_date":"2017-04-20","publish_status":"0","recid":"47750","relation_version_is_last":true,"title":["Graft-type polymer electrolyte membranes based on poly(ether ether ketone)/nanosilica hybrid films for fuel cell applications"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:35:57.198853+00:00"}
