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, an aqueous coating (15, 16) is applied onto a microporous substrate (10) for a gas diffusion layer. The coating comprises a catalyst as well as a first polymeric binder that is only water soluble below a first temperature T1 and a second polymeric binder that is only water soluble above a second temperature T2, wherein T2>T1. When preparing the coating, the first and second polymeric binders are added to an aqueous base in separate stages, where the temperature of the aqueous base is below T1 when adding the first polymeric binder and above T2 when adding the second polymeric binder. By heating the coating, the two polymers are cross linked, which prevents dissolution of the two polymeric binders.[French]
L'invention concerne une électrode, son procédé de production et une pile à combustible dotée d'une telle électrode ; dans un procédé de production d'électrodes (20), par exemple pour des piles à combustible, un revêtement aqueux (15, 16) est appliqué sur un substrat microporeux (10) pour une couche de diffusion de gaz. Le revêtement comprend un catalyseur ainsi qu'un premier liant polymère qui est uniquement soluble dans l'eau en dessous d'une première température T1 et un second liant polymère qui est uniquement soluble dans l'eau au-dessus d'une seconde température T2, T2 > T1. Lors de la préparation du revêtement, les premier et second liants polymères sont ajoutés à une base aqueuse dans des étapes distinctes, la température de la base aqueuse étant inférieure à T1 lors de l'ajout du premier liant polymère et supérieure à T2 lors de l'ajout du second liant polymère. En chauffant le revêtement, les deux polymères sont réticulés, ce qui empêche la dissolution des deux liants polymères.
