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 comprises a plate having an aperture and means for mounting a thin film 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.
