The invention relates to an ion-conductive polymer membrane for a fuel cell, whereby the polymer membrane is configured from a polymer-forming hydrocarbon material and to a method for producing the same. The membrane also has a metal- containing gel which has been hydrolysed and/or condensed from a metal alkoxide starting material and which is deposited in the polymer and/or is chemically bonded to the polymer. The proportion of metal alkoxide by weight, in relation to the membrane, lies between 25 % and 1 %.
L'invention concerne une membrane polymère conductrice ionique pour pile à combustible, réalisée en un matériau hydrocarboné formant un polymère, ainsi qu'un procédé pour sa fabrication. La membrane présente en outre un gel métallifère qui a été hydrolysé et/ou condensé à partir d'un matériau de départ alcoxyde métallique, et qui est déposé dans le polymère et/ou chimiquement lié à celui-ci, la proportion pondérale en alcoxyde métallique étant comprise entre 25 % et 1 % par rapport à la membrane.
