Abstract[English]
The invention relates to a method to produce an electrochemical cell (1), in particular an electrolysis cell, comprising a catalyst-coated membrane (2) and porous transport layers (3) arranged on both sides of the membrane (2). At least one side of at least one porous transport layer (3), preferably the side facing the catalyst-coated membrane (2), is subjected to laser treatment, in which surface contamination (4) is removed with the aid of a laser (5).[French]
L'invention concerne un procédé de production d'une cellule électrochimique (1), en particulier une cellule d'électrolyse, comportant une membrane revêtue de catalyseur (2) et des couches de transport poreuses (3) disposées des deux côtés de la membrane (2). Au moins un côté d'au moins une couche de transport poreuse (3), de préférence le côté faisant face à la membrane revêtue de catalyseur (2), est soumis à un traitement laser dans lequel une contamination de surface (4) est éliminée à l'aide d'un laser (5).
