Abstract[English]
An electrode, a method of producing it, and a fuel cell with such elec- trode In a method of producing electrodes (20), for example for fuel cells, two aqueous coatings (15, 16) are subsequently applied onto a porous hydrophobic electroconductive substrate (10). A first coating containing a sacrificial hydrophilic polymer, for example HEC and/or PPC, is applied for temporarily hydrophilizing the substrate surface. For providing a catalyst layer, CL, a second coating is applied on the first coating. The sec- ond coating comprises an electroconductive filler and a catalyst and water soluble polymeric binders, for example PVA and HPC. By heating the coatings, the sacrificial pol- ymer decomposes and evaporates and binds the catalyst layer to the substrate.[French]
L'invention concerne une électrode, son procédé de production et une pile à combustible avec une telle électrode dans un procédé de production d'électrodes (20), par exemple pour des piles à combustible, deux revêtements aqueux (15, 16) sont ensuite appliqués sur un substrat électroconducteur hydrophobe poreux (10). Un premier revêtement contenant un polymère hydrophile sacrificiel, par exemple HEC et/ou PPC, est appliqué pour hydrophiliser temporairement la surface de substrat. Pour fournir une couche de catalyseur CL, un second revêtement est appliqué sur le premier revêtement. Le second revêtement comprend une charge électroconductrice et un catalyseur et des liants polymères solubles dans l'eau, par exemple du PVA et du HPC. En chauffant les revêtements, le polymère sacrificiel se décompose et évapore et lie la couche de catalyseur au substrat.
