METHOD FOR PRODUCING A MEMBRANE ELECTRODE ASSEMBLY

The invention relates to a method for producing membrane electrode assemblies (MEA) for fuel cells (101), in particular in a continuous flow path process, comprising the following steps: 1) providing a band-shaped membrane material (M) in a flow path direction (D), e.g. on a roller, such that in par...

Zusammenfassung:	The invention relates to a method for producing membrane electrode assemblies (MEA) for fuel cells (101), in particular in a continuous flow path process, comprising the following steps: 1) providing a band-shaped membrane material (M) in a flow path direction (D), e.g. on a roller, such that in particular the membrane material (M) can be unwound from the roller in the flow path process, 2) coating the band-shaped membrane material (M) with an active material (E), 3) cutting the coated membrane material (M) into individual membrane electrode assemblies (MEA), such that the individual membrane electrode assemblies (MEA) are formed with at least one edge region (TR), which is formed so as to be curved and/or angled when viewed in the flow path direction (D).
