Abstract
The present invention relates to membrane electrode assemblies comprising two electrochemically active electrodes separated by a polymer electrolyte membrane, there being a polyimide layer on each of the two surfaces of the polymer electrolyte membrane that are in contact with the electrodes. The present membrane electrode assemblies may be used in particular for producing fuel cells which have a particularly high long-term stability.
