简介 The invention relates to a layer system for isolating hydrogen from gases containing hydrogen and to an associated production method. The layer system consists of two proton conducting, gas-tight layers. A functional layer consisting of a material with a high proton conductivity, which is however sensitive to process gases such as CO2 or aggressive trace gases, constitutes the largest proportion of the thickness of the layer system. Said layer is protected by a thin protective layer consisting of a material whose proton conductivity is lower but which is insensitive to reactive gases. Said layer system permits an improved proton conductivity to be obtained with a predefined gas tightness and total thickness of the layer in relation to prior art. In the production method, an alkaline-earth metal carbonate is reduced to form an oxide, which has solid-state reactions with previously applied layers of zirconium or rare earth metals. The protective layer and functional layer are produced by sintering.
