Grafted polymer electrolyte membrane, method for the production thereof, and application thereof in fuel cells

摘要

The present invention relates to a proton-conducting polymer electrolyte membrane based on polyvinylphosphonic acid/polyvinylsulfonic acid polymers, which owing to their excellent chemical and thermal properties, can be used for a variety of purposes and is particularly suitable as polymer electrolyte membrane (PEM) in PEM fuel cells.
