Method for producing a membrane made of bridged polymer and a fuel cell. The present invention relates to a 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/tensile strength) with virtually unchanged swelling behavior. The membranes of the invention are suitable for producing membrane-electrode units for fuel cells.
