CA 2496654

Fixtures and methods of using fixtures to facilitate the fabrication of devices having thin films, for example, gasketed components of fuel-cell membrane electrode assemblies, are disclosed. In one aspect, the fixture (10) comprises a plate (12) having an aperture (14) and means (16) for mounting a thin film (17) to the plate wherein the thin film at least partially obstructs the aperture and wherein the thin film provides a surface for mounting at least one component of a device. Another aspect is a fixture for facilitating the fabrication of a fuel-cell membrane electrode assembly which includes a plate having an aperture and means for mounting a gasket to the plate wherein the gasket at least partially obstructs the aperture and wherein the gasket provides a surface for mounting at least one electrode for a fuel-cell membrane electrode assembly.

L'invention concerne des éléments de retenue et des procédés d'utilisation d'éléments de retenue facilitant la fabrication de dispositifs comprenant des couches minces, tels que, par exemple, des composants à joint d'étanchéité d'ensembles d'électrodes à membrane de piles à combustible. Dans un aspect, l'élément de retenue comprend une plaque pourvue d'une ouverture et des moyens destinés à monter une couche mince sur cette plaque, la couche mince obstruant au moins partiellement l'ouverture, cette couche mince fournissant une surface permettant de monter au moins un composant d'un dispositif. Dans un autre aspect, l'invention concerne un élément de retenue facilitant la fabrication d'un ensemble d'électrodes à membrane de pile à combustible et comprenant une plaque pourvue d'une ouverture et des moyens destinés au montage d'un joint d'étanchéité sur cette plaque, ce joint d'étanchéité obstruant au moins partiellement l'ouverture, ledit joint fournissant une surface permettant de monter au moins une électrode pour un ensemble d'électrodes à membrane de pile à combustible.
