Abstract
The present invention relates to novel polymer blend membranes comprising a functional polymer based on sulfonated aryl polymers, a reinforcing polymer based on aminated or nitrated polyether sulfones and/or polyether ether sulfone and a plasticizer, and also their use as polymer electrolyte membrane in fuel cells, in particular in low-temperature fuel cells.
