Title
(EN) PROCESS OF MANUFACTURING A CATALYST-COATED MEMBRANE-SEAL ASSEMBLY
(FR) PROCÉDÉ DE FABRICATION D'UN ENSEMBLE MEMBRANE-JOINT REVÊTU D'UN CATALYSEUR
Abstract
(EN) A process for the manufacture of a catalyst-coated membrane-seal assembly, said process comprising the steps of: (i) providing a carrier material; (ii-i) forming a first layer, said first layer being formed by: (a) depositing a first catalyst component onto the carrier material such that the first catalyst component is deposited in discrete regions; (b) drying the first layer; (ii-ii) forming a second layer, said second layer being formed by: (a) depositing a first seal component, such that the first seal component provides a picture frame pattern having a continuous region and void regions, the continuous region comprising second seal component and the void regions being free from second seal component; (b) depositing a first ionomer component onto the first layer, such that the first ionomer component is deposited in discrete regions; and (c) drying the second layer; wherein the void regions of the first seal component are centrally positioned over the discrete regions of the first ionomer component; wherein the discrete regions of the first ionomer component are centrally positioned over the discrete regions of the first catalyst component; and wherein steps (ii-ii)(a) and (ii-ii)(b) are carried out in either order; (iii) removing the carrier material.; is disclosed.
(FR) L'invention concerne un procédé de fabrication d'un ensemble membrane-joint revêtu d'un catalyseur, ledit procédé comprenant les étapes consistant à : (i) fournir un matériau de support ; (ii-i) former une première couche, ladite première couche étant formée en : (a) déposant un premier composant de catalyseur sur le matériau de support de telle sorte que le premier composant de catalyseur est déposé dans des régions discrètes ; (b) séchant la première couche ; (ii-ii) former une seconde couche, ladite seconde couche étant formée en : (a) déposant un premier composant de joint, de telle sorte que le premier composant de joint fournit un motif d'encadrement comportant une région continue et des régions de vide, la région continue comprenant un second composant de joint et les régions de vide étant exemptes du second composant de joint ; (b) déposant un premier composant d'ionomère sur la première couche, de telle sorte que le premier composant d'ionomère est déposé dans des régions discrètes ; et (c) en séchant la seconde couche ; les régions de vide du premier composant de joint étant positionnées centralement sur les régions discrètes du premier composant d'ionomère ; les régions discrètes du premier composant d'ionomère étant positionnées centralement sur les régions discrètes du premier composant de catalyseur ; et les étapes (ii-ii)(a) et (ii-ii)(b) étant effectuées dans un ordre quelconque ; (iii) retirer le matériau de support.
