MULTILAYERED STRUCTURES AND METHODS FOR PRODUCING THE SAME
The invention relates to methods for producing membranes, methods for producing membrane electrode units and membranes produced by these methods. The claimed membranes and membrane electrode units may be used to produce energy electrochemically or photochemically, in particular in membrane fuel cells (H2 or direct methanol fuel cells) at temperatures from 20 to +180 DEG C. In one embodiment, working temperatures of up to 250 DEG C are possible. The claimed membranes and membrane electrode units can be used in membrane methods, in particular in galvanic cells, in secondary batteries, in electrolysis cells, in membrane separation processes such as gas separation, pervaporation, perstraction, reverse osmosis, electrodialysis, diffusion dialysis and for the separation of alkene-alkane mixtures or for the separation of mixtures of which one component forms complexes with silver ions.
