Abstract

A method for producing a membrane electrode assembly for a fuel cell includes providing a first component of the membrane electrode assembly as part of a continuous material web which passes through a plurality of processing stations and connecting a second component of the membrane electrode assembly to the first component by a firmly bonded connection.

Claims (8)

1. A method for producing a membrane electrode assembly for a fuel cell, comprising the steps of:

providing a first component of the membrane electrode assembly as part of a continuous material web which passes through a plurality of processing stations, wherein the first component is a frame material, wherein the frame material forms a frame of the membrane electrode assembly, and wherein the frame encloses an active region of the membrane electrode assembly;

connecting a second component of the membrane electrode assembly to the frame material by a first adhesive applied to the frame material, wherein the second component is a membrane with a catalyst material; and

applying the first adhesive to the membrane and connecting a gas diffusion element to the membrane by the first adhesive.

2. The method according to claim 1 , wherein the frame material is connected to a carrier web by a second adhesive, wherein a base web is formed by the frame material connected to the carrier web.

3. The method according to claim 1 , wherein a reference element is applied to at least one of the first and the second components of the membrane electrode assembly by printing.

4. The method according to claim 1 , wherein the first adhesive is applied by a printing method.

5. The method according to claim 4 , wherein the printing method is a silk-screen printing method.
