METHOD FOR PRODUCING A MEMBRANE FROM A CROSS-LINKED POLYMER BLEND, AND CORRESPONDING FUEL CELL

摘要

The present invention relates to a polymer blend membrane comprising a bridged polymer which is produced by a selected process. The membrane of the invention displays a significantly improved fracture toughness (elongation at break/stress) combined with virtually unchanged other properties. The membranes of the invention are suitable for producing membrane-electrode units for fuel cells.
