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

A method for producing a membrane electrode assembly of a fuel cell, wherein the membrane electrode assembly includes an anode, a cathode, and a catalyst-coated polymer electrolyte membrane disposed between the anode and the cathode, comprising the steps of:

• coating a polymer electrolyte membrane with a catalyst material to form the catalyst-coated polymer electrolyte membrane;
• detecting a defective point of a surface of the catalyst-coated polymer electrode membrane;
• conveying the catalyst-coated polymer electrolyte membrane as a continuous material in a conveying direction;
• performing targeted reprinting, by a non-contact printing method, of the catalyst material directly onto a surface of the catalyst-coated polymer electrolyte membrane at the defective point of the surface while the catalyst-coated polymer electrolyte membrane is continuously conveyed in the conveying direction;
• and
• following the printing, during continuous production of the membrane electrode assembly, dispensing a gas diffusion layer by way of a dispensing module to a printed catalyst-coated polymer electrolyte electrode to produce the membrane electrode assembly.
