The invention relates to a membrane which contains crosslinked phosphonated pentafluorostyrene. The invention also relates to the use of a membrane or membrane electrodes containing crosslinked phosphonated pentafluorostyrene in an electrochemical cell at a temperature of 0 to 380° C. The invention also describes the use of a membrane or membrane electrodes containing non-crosslinked phosphonated pentafluorostyrene in an electrochemical cell at a temperature of 0 to 380° C. In addition, the invention discloses a nonwoven fabric containing phosphonated polypentafluorostyrene. The invention also relates to the use of the nonwoven fabric in a membrane or in a membrane electrode unit in electrochemical applications at temperatures up to 380° C.
