Abstract[German]
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Gasdiffusionslage für eine Brennstoffzelle auf Basis eines flächigen elektrisch leitfähigen Fasermaterials mit einer guten Einbindung der Fasern in das Fasermaterial. Die Erfindung betrifft weiterhin die nach diesem Verfahren erhältlichen Gasdiffusionslagen, eine Brennstoffzelle, die eine solche Gasdiffusionslage enthält sowie einen Brennstoffzellstapel, der wenigstens zwei solche Brennstoffzellen enthält.[English]
The present invention relates to a method for producing a gas diffusion layer for a fuel cell on the basis of a flat, electrically conductive fibre material with good bonding of the fibres in the fibre material. The invention furthermore relates to the gas diffusion layers which can be obtained according to this method, to a fuel cell which contains such a gas diffusion layer, and to a fuel cell stack which contains at least two such fuel cells.[French]
La présente invention concerne un procédé de production d'une couche de diffusion gazeuse pour une pile à combustible sur la base d'un matériau fibreux électroconducteur plat présentant une bonne liaison des fibres dans le matériau fibreux. L'invention concerne en outre les couches de diffusion gazeuse qui peuvent être obtenues selon ce procédé, une pile à combustible qui contient une telle couche de diffusion gazeuse, et un empilement de piles à combustible qui contient au moins deux piles à combustible de ce type.
