Method for the production of a membrane electrode assembly for a fuel cell

Abstract

A method for providing a catalyst-coated polymer electrolyte membrane for a membrane electrode assembly of a fuel cell with at least one functional coating made of a material includes printing directly the material onto the catalyst-coated polymer electrolyte membrane by a non-contact printing method.

1 . A method for producing a membrane electrode assembly for a fuel cell, comprising the steps of:
 providing a frame material which forms a frame of the membrane electrode assembly, wherein the frame encloses an active region of the membrane electrode assembly; and   providing a partial region of the frame material with a functional coating produced from a material wherein the material is printed directly onto the frame material.   
     
     
         2 . The method according to  claim 1 , wherein the frame material is provided as a continuous material web which passes through a plurality of processing stations. 
     
     
         3 . The method according to  claim 1 , wherein the material is an adhesive and wherein the frame material is connected to a component of the membrane electrode assembly by the adhesive. 
     
     
         4 . The method according to  claim 3 , wherein the material is an adhesive and wherein the adhesive is printed with a thickness of less than 100 μm.
