  • Method for manufacturing a membrane assembly for a fuel cell with catalyst free edge areas; membrane assembly and fuel cell with membrane assembly
    Patent number: 11201344
    Abstract: A method for manufacturing a membrane assembly for a fuel cell. To overcome a problem of chemical degradation at an edge of the membrane, the method comprises the following steps: positioning a first decal layer, which is made of the same material as a first catalyst layer, on a first side of the membrane, positioning a second decal layer, which is made of the same material as a second catalyst layer, on a second side of the membrane, pressing a compression pad, which is positioned on the first decal layer with the first decal layer and the second decal layer fully overlapping the compression pad, and the second decal layer against each other with the first decal layer and the membrane positioned in-between, whereby pressure on the first and the second decal layer is applied only in an area covered by the compression pad.
