Abstract[English]
There is provided a method of preparing an ion-conducting membrane layer for a fuel cell or an electrolyser. The method comprises the steps of: (i) providing a donor substrate having opposing first and second surfaces and providing an ink disposed as a layer on the second surface, wherein the ink comprises a radiation absorber, an ion-conducting polymer, and a solvent; (ii) providing an acceptor substrate, wherein the second surface of the donor substrate faces towards the acceptor substrate; and (iii) irradiating the ink with laser radiation at a wavelength which is absorbed by the radiation absorber so as to transfer the ink from the donor substrate to the acceptor substrate.[French]
L'invention concerne un procédé de préparation d'une couche de membrane conductrice d'ions pour une pile à combustible ou un électrolyseur. Le procédé comprend les étapes consistant à : (i) fournir un substrat donneur ayant des première et seconde surfaces opposées et fournir une encre disposée en couche sur la seconde surface, l'encre comprenant un absorbeur de rayonnement, un polymère conducteur d'ions et un solvant ; (ii) fournir un substrat accepteur, la seconde surface du substrat donneur étant orientée vers le substrat accepteur ; et (iii) exposer l'encre à un rayonnement laser à une longueur d'onde qui est absorbée par l'absorbeur de rayonnement de façon à transférer l'encre du substrat donneur vers le substrat accepteur.
