Title:
METHOD FOR PREPARING MEMBRANE-ELECTRODE ASSEMBLY, MEMBRANE-ELECTRODE ASSEMBLY PREPARED THEREFROM, AND FUEL CELL COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/101591
Kind Code:
A1
Abstract:
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.
