The invention relates to a membrane electrode assembly for a fuel cell, in particular a PEM fuel cell and to a method for producing the same. According to said method, the expensive precious metal (3) is distributed asymmetrically over the membrane (1) according to the requirements of each area. The production method is characterised in that the electrodes are first coated with the membrane and not vice versa.
L'invention concerne une unité membrane-électrodes pour une pile à combustible, en particulier un pile à combustible avec membrane électrolytique en polymère (PEM), ainsi qu'un procédé de fabrication. Selon l'invention, le métal précieux, onéreux, est réparti sur la membrane de manière asymétrique, en fonction du besoin de la zone correspondante. Le procédé de fabrication est caractérisé en ce que les électrodes sont tout d'abord recouvertes par la membrane et non l'inverse.
