Abstract
The present invention relates to a novel proton-conducting polymer membrane based on polyazoles which can, owing to its excellent chemical and thermal properties, be used for a variety of purposes and is particularly suitable as a polymer-electrolyte membrane (PEM) for the production of membrane electrode units for so-called PEM fuel cells.
