METHOD FOR PRODUCING A MEMBRANE ELECTRODE ASSEMBLY FOR A FUEL CELL

Method for producing a membrane electrode assembly (100) for a fuel cell, comprising a proton exchange polymer membrane (10), catalytic layers (20, 30) and first and second gas diffusion layers (50, 40), the method comprising the following steps: a) forming a catalytic layer coating (20) on a first surface (14) of the membrane, the opposite surface (15) being supported by a spacer (12); b) forming a catalytic layer coating (30) on a first surface (54) of the first gas diffusion layer (50); c) bringing the first surface (54) of the first gas diffusion layer (50) into contact with the surface (15) opposite to the first surface (14) of the membrane, after removing the spacer (12), and bringing the first surface (14) of the membrane into contact with a surface of the second gas diffusion layer (40). 一种生产燃料电池的膜电极组件(100)的方法，所述膜电极组件包含聚合物质子交换膜(10)、催化层(20、30)，以及第一和第二气体扩散层(50、40)，所述方法包括以下步骤：a)在所述膜的第一表面(14)上形成催化层(20)，相对表面(15)由垫片(12)支承；b)在所述第一气体扩散层(50)的第一表面(54)上形成催化层(30)；c)在去除所述垫片(12)之后，使第一气体扩散层(50)的第一表面(54)与所述膜的第一表面(14)
