Abstract: A sheet-like substrate (34) is coated with at least one thin film (36?) composed of at least one porous ceramic layer (S?1, S?2, S?3, . . . ). A solution or a suspension of an organic and/or inorganic metal composite as starting material (14) is admixed with a mixed-in, insoluble pore former (18) and the mixture (22) is sprayed on as layer (S?1, S?2, S?3, . . . ) of a thin film (36). The pore former (18) is at least partly thermally decomposed and/or burnt out to form an at least partly open-pored structure. The process is particularly suitable for producing miniaturized devices such as fuel cells and gas sensors.

All layers of the thin film have a maximum average particle size of approximately 500 nm and at least two layers consist of different material. In at least one of said layers, an essentially stable average particle size remains after a relaxation time, even in an increased temperature range. The mechanical stability is preferably reinforced by a supporting, essentially flat substrate. In the composite element, the thickness of the substrate is at least five times and in particular between ten and a hundred times the thickness of the thin film. The composite element can be successfully used in a miniaturised electrochemical device, in particular in a solid oxide fuel cell SOFC, a sensor or as a gas separation membrane.
