Abstract: A fuel cell membrane is described comprising at least one sulfonated aromatic polyether copolymer comprising a poly-arylen-ether-ketone (PEK) moiety or sulfonated derivatives thereof, deriving from spiro-bis-indane or 4,4′-(hexafluoroisopropylidene)diphenol (BPAF), and an arylene-sulfone, or an arylene-ketone or sulfonated derivative thereof; said copolymer having the following formula (1): wherein Ar1 has formula, wherein X is spiro-bis-indanile (SBI) (b) or BPAF (c) having formulas: and wherein Y is H or SO3H, and Ar2 has formula wherein W is CO or SO2, and Y is H or SO3H, wherein Z is OH or Cl; and wherein at least one between Ar1 or Ar2 comprise at least one sulfonic group; and wherein n is an integer comprised between 2 and 50. A method for the production of such membrane is also described.
