    • 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.
    • 目的:提供一种用于燃料电池的膜 - 电极组件,以减少电解质膜和电催化剂层之间的界面电阻,并通过后处理工艺确保电催化剂层内的孔隙。 构成:一种用于制造燃料电池用膜电极组件(100)的方法,包括以下步骤:在第一支撑膜(200)上形成第一电极催化剂层(102),并通过施加形成第一离子传导层 在第一电极催化剂层上形成离子传导材料以制备第一转印膜; 在第二支撑膜(200')上形成第二电极催化剂层(102'),并通过在第二电极催化剂层上施加离子传导材料形成第二离子传导层(103')以制备第二转印膜; 并且将第一转印膜的第一离子传导层和第二转印膜的第二离子传导层分别布置在电解质膜(101)的一侧和另一侧,同时或相继转印。
