Abstract: front page image
(EN)A polyelectrolyte film for solid polymer type fuel cells, characterized by comprising an aromatic polyethersulfone block copolymer comprising a hydrophilic segment containing sulfo groups and a hydrophobic segment containing no sulfo group, the hydrophilic segment having a structure comprising structural units represented by the following chemical formula (1) and sulfo groups introduced therein as substituents.
(FR)Il est prévu un film polyélectrolytique pour cellules électrochimiques de type polymère solide, caractérisé en ce qu’il comprend un copolymère bloc de polyéther sulfone aromatique contenant un segment hydrophile englobant des groupes sulfonés et un segment hydrophobe ne contenant pas de groupe sulfoné, le segment hydrophile ayant une structure comprenant des unités structurelles représentées par la formule chimique suivante (1) et des groupes sulfonés introduits dans celle-ci comme éléments substitutifs. [Formule chimique 1] (1)
(JA) スルホン酸基を含有する親水性セグメントとスルホン酸基を含有しない疎水性セグメントとからなり、上記親水性セグメントが、下記化学式(1)からなる構造単位に置換基としてスルホン酸基が導入された構造を有する芳香族ポリエーテルスルホンブロック共重合体からなることを特徴とする固体高分子型燃料電池用高分子電解質膜。 【化1】
