A method for producing an electrode material for gas diffusion layers, to the electrode material thereby produced and to its use.

Electrode material

Membrane electrode assembly for PEM fuel cells, including a proton exchange membrane, two catalyst layers (anode and cathode catalyst layer), and two gas diffusion layers, the anodic one of which is based on a carbon fiber paper and is provided with a microporous layer including graphite, carbon nanotubes or carbon nanofibers, and PTFE, whereas the cathodic gas diffusion layer is based on a carbon fiber structure and is provided with a microporous layer based on carbon black, carbon nanotubes and/or carbon nanofibers, and PTFE.

Membrane electrode assembly

A carbon-fiber-based gas diffusion layer (GDL) for use in polymer electrolyte membrane (PEM) fuel cells (FC) having structured hydrophilic properties, wherein materials with hydrophilic properties and selected from the group of metal oxides in an average domain size of 0.5 to 80 &#x3bc;m are present as hydrophilic wicks in the gas diffusion layer.
