Abstract
The invention relates to a method for manufacturing a membrane electrode assembly for a fuel cell, which membrane electrode assembly comprises a membrane (2) with a catalyst layer (3) and a frame (6) arranged on the same side of the membrane (2) and a gap (5) between the catalyst layer (3) and the frame (6). To allow an easy and cost-effective way for manufacturing such a membrane assembly, the manufacturing method comprises the following steps: *- Positioning a first decal layer (10, 13), which is made of the same material as the first catalyst layer (3), on the first side of the membrane (2) in a way that the first decal layer (10, 13) overlaps the frame (6), *- positioning a second decal layer (10, 14), which is made of the same material as the second catalyst layer (4), on the second side of the membrane (2), *- pressing the first decal layer (10, 13) and the second decal layer (10, 14) against each other with the membrane (2) and the frame (6) positioned in-between.
