Zusammenfassung:	A method and apparatus for handling thin films, for example, for handling and assembling membranes in fuel cell electrodes. The apparatus includes a translatable vacuum table for mounting the thin film, a perforated drum having a source of vacuum for removing the thin film from the vacuum table, and a transfer assembly having a perforated surface and a source of vacuum for transferring the thin film from the perforated drum to a target location. When the thin films are provided in containers, the apparatus may also include means for opening the containers to access the thin film within. Removal of the thin film from the transfer assembly may be aided by a thin film release device, for example, a plurality of moveable wires. The apparatus may be automated, for example, the apparatus may include automated controllers and robotic arms to facilitate the handling of thin film materials. Procédé et dispositif de manipulation de films minces, utiles par exemple pour manipuler et assembler des membranes dans des électrodes de pile à combustible. Le dispositif comprend une table aspirante pouvant effectuer un mouvement de translation et destinée à fixer le film mince, un tambour perforé comportant une source de vide pour détacher le film mince de la table aspirante, et un ensemble transfert comportant une surface perforée et une source de vide pour transférer le film mince du tambour perforé vers un lieu cible. Lorsque les films minces sont fournis dans des contenants, le dispositif peut aussi comprendre des moyens d'ouverture des contenants pour accéder au film contenu dans ceux-ci. L'étape consistant à détacher le film mince, mise en oeuvre par l'ensemble transfert, peut être facilitée par un système de libération de film mince, tel qu'une pluralité de fils métalliques déplaçables. Le dispositif peut être automatisé, et peut comprendre par exemple des organes de commande automatisés et des bras manipulateurs pour faciliter la manipulation des matières de films minces.
