(FR) PROCÉDÉ DE PRÉPARATION D’UN ENSEMBLE MEMBRANE-ÉLECTRODE, ENSEMBLE MEMBRANE-ÉLECTRODE PRÉPARÉ SELON CELUI-CI, ET PILE À COMBUSTIBLE COMPRENANT CELUI-CI
(KO) 막-전극 접합체 제조방법, 이로부터 제조된 막-전극 접합체 및 이를 포함한 연료전지
Abstract: front page image
(EN)The present invention relates to a method for preparing a membrane-electrode assembly, a membrane-electrode assembly prepared therefrom, and a fuel cell comprising same. The method for preparing a membrane-electrode assembly additionally comprises a step of, after drying a catalyst slurry composition and then adding solvent B thereto, re-homogenizing the catalyst slurry composition by sonication, and thus can improve the dispersibility of ionomer.
(FR)La présente invention concerne un procédé de préparation d’un ensemble membrane-électrode, un ensemble membrane-électrode préparé selon celui-ci, et une pile à combustible comprenant celui-ci. Le procédé de préparation d’un ensemble membrane-électrode comprend en outre une étape, après séchage d’une composition de suspension concentrée de catalyseur puis ajout d’un solvant B à celle-ci, de réhomogénéisation de la composition de suspension concentrée de catalyseur par sonication, et peut ainsi améliorer la dispersibilité de l’ionomère.
(KO)본 발명은 막-전극 접합체의 제조방법, 이로부터 제조된 막-전극 접합체 및 이를 포함한 연료전지에 관한 것으로, 상기 막-전극 접합체의 제조방법은 촉매 슬러리 조성물을 건조한 이후에, 용매 B를 첨가한 후 초음파 처리하여 재균일화하는 단계를 추가함으로써, 이오노머의 분산성을 향상시킬 수 있다.
