Abstract[English]
A method for recycling a catalyst coated membrane comprising an ionomer membrane coated on either side by catalyst layers, the method comprising: soaking the catalyst coated membrane in a first solvent; transferring the catalyst coated membrane from the first solvent into a second solvent which is different to the first solvent; and subjecting the catalyst coated membrane in the second solvent to an ultrasonic treatment to delaminate the catalyst layers from the ionomer membrane.[French]
La présente invention concerne un procédé de recyclage d'une membrane revêtue d'un catalyseur, comprenant une membrane en ionomère revêtue de part et d'autre de couches de catalyseur, le procédé comprenant les étapes consistant à : tremper la membrane revêtue d'un catalyseur dans un premier solvant ; transférer la membrane revêtue de catalyseur du premier solvant dans un second solvant différent du premier solvant ; et soumettre la membrane revêtue de catalyseur dans le second solvant à un traitement par ultrasons afin de délaminer les couches de catalyseur de la membrane en ionomère.
