Abstract An ionically conductive polymer is a copolymer including first and second polymer segments. The first polymer segments have a hydrophobic character and a high oxygen permeability. The second polymer segments have a hydrophilic character and a low oxygen permeability. The copolymer has an ionic conductivity of at least about 1 x 10-5 S/cm at any point within a temperature range of from 30°C to 15O°C and a relative humidity range of from 20% to 100%. The ionically conductive polymer can be used in an electrochemical device such as a fuel cell, for example, used as a binder in an electrode or used to produce a membrane. L'invention porte sur un polymère ioniquement conducteur qui est un copolymère comprenant des premiers et seconds segments de polymère. Les premiers segments de polymère ont un caractère hydrophobe et une perméabilité à l'oxygène élevée. Les seconds segments de polymère ont un caractère hydrophile et une faible perméabilité à l'oxygène. Le copolymère a une conductivité ionique d'au moins environ 1 x 10-5 S/cm à n'importe quel point dans une plage de températures de 30 °C à 150 °C et une plage d'humidité relative de 20 % à 100 %. Le polymère ioniquement conducteur peut être utilisé dans un dispositif électrochimique tel qu'une pile à combustible, par exemple, utilisé en tant que liant dans une électrode ou utilisé pour produire une membrane.
