ABSTRACT:
The invention relates to a membrane, in particular, a membrane for use in a methanol fuel cell. The inventive membrane comprises complexing agents for cations and, therefore, functions like an anion exchanger. In a particular embodiment, the membrane comprises complexing agents selected from the group of crown ethers, cryptates, or of cryptate-like compounds based on carbon cyclic compounds or silicon compounds.
