Abstract[English]
According to the present invention there is provided a method of producing a catalyst-containing layer for a fuel cell or electrolyser. The method comprising the steps of: • providing a flow of ink from an ink container (52), the ink comprising catalyst particles, an ion-conducting polymer and a liquid medium; • conveying the flow of the ink through a density separator (54) configured to separate contaminant particles from the flow of ink, wherein the contaminant particles are more dense than the catalyst particles; and then • coating the ink onto a substrate by means of a coating device (56).[French]
Selon la présente invention, un procédé de production d'une couche contenant un catalyseur pour une pile à combustible ou un électrolyseur est fourni. Le procédé comprend les étapes consistant à : fournir un flux d'encre à partir d'un récipient d'encre (52), l'encre comprenant des particules de catalyseur, un polymère conducteur d'ions et un milieu liquide ; transporter le flux de l'encre à travers un séparateur de densité (54) configuré pour séparer des particules contaminantes du flux d'encre, les particules de contaminants étant plus denses que les particules de catalyseur ; puis revêtir l'encre sur un substrat au moyen d'un dispositif de revêtement (56).
