Disclosed are an electrolyte polymer for fuel cells having excellent durability, an electrolyte membrane and a membrane electrode assembly. Specifically disclosed is an electrolyte polymer for fuel cells which is composed of a perfluorocarbon polymer having an ion exchange group (which may contain an ether oxygen atom) and characterized in that the value obtained by dividing the absorbance area (SCH) mainly ascribed to C-H bonds, which is measured within the range from 3100 cm-1 to 2800 cm-1 by infrared spectroscopy, by the peak absorbance area (SCF) mainly ascribed to C-F bonds, which is measured within the range from 2700 cm-1 to 2000 cm-1, is less than 0.005.
L'invention porte sur un polymère électrolytique pour piles à combustible d'une excellente durabilité, une membrane électrolytique et un ensemble électrode à membrane. L'invention porte spécifiquement sur un polymère électrolytique pour piles à combustible composé d'un polymère de perfluorocarbone ayant un groupe d'échange ionique (susceptible de contenir un atome d'oxygène d'éther) et caractérisé en ce que la valeur obtenue en divisant la zone d'absorbance (S<SB>CH</SB>) principalement attribuée aux liaisons C-H, que l'on mesure dans la fourchette allant de 3100 cm-1 à 2800 cm-1 par spectroscopie infrarouge, par la zone d'absorbance de pointe (S<SB>CF</SB>) principalement attribuée aux liaisons C-F, que l'on mesure dans la fourchette allant de 2700 cm-1 à 2000 cm-1, est inférieure à 0,005.
