MEMBRANE AND ELECTRODE ASSEMBLY FOR FUEL CELL, MANUFACTURING METHOD, AND FUEL CELL USING THE SAME

摘要

PURPOSE: A membrane-electrode assembly for a fuel cell is provided to reduce the interface resistance between an electrolyte film and an electrocatalyst layer, and to securer porosity within the electrocatalyst layer through post-treatment process. CONSTITUTION: A method for manufacturing a membrane-electrode assembly(100) for a fuel cell comprises the steps of: forming a first electrode catalyst layer(102) on a first support film(200) and forming a first ion-conductive layer by applying ion conductive materials on the first electrode catalyst layer to prepare a first transfer film; forming a second electrode catalyst layer(102') on a second support film(200') and forming a second ion-conductive layer(103') by applying ion conductive materials on the second electrode catalyst layer to prepare a second transfer film; and respectively arranging the first ion-conductive layer of the first transfer film and the second ion-conductive layer of the second transfer film on one side and the other side of an electrolytic membrane(101) and simultaneously or successively transferring them.
