    Abstract: A method for preparing a membrane to be assembled in a membrane electrode assembly is disclosed, comprising the steps of : a) irradiating sections (4) of a polymer film (2) with electromagnetic and/or particle radiation with a predetermined irradiation profile in order to both define irradiated sections (4) and to form reactive centers, i.e. radicals, in said irradiated sections (4) of the membrane; thereby separating the irradiated sections (4) from each other by separation bands (6) of un-irradiated membrane sections; b) exposing the film (2) comprising the irradiated sections (4) to a monomer or a mixture of monomers amenable to radical polymerization in order to achieve the formation of a graft copolymer in said irradiated sections (4). This method and the respective assembly yield a membrane that has, due to the profile of the irradiation, separated regions of distinct and appropriate properties to serve as a fuel cell electrolyte. It is therefore possible to generate within the same membrane layer or membrane film sections which have in its swollen state pro ton- conductive properties adjacent to the separation band sections which are the remaining original insulating starting material. This allows to generate within a single layer a plurality of separate fuel cells. Furthermore, this method allows to achieve additional property gradients, such as conductivity, water uptake, etc., within the same "activated" section and also over the thickness of the membrane for the purpose of asymmetric grafting.

    Abstract: The present invention relates to methods of fabricating composite membranes wherein at least one of the components is initially provided in the form of a precursor. The composite material comprising the precursor is processed to transform the precursor and obtain a membrane having a desired property. Including a thermoplastic precursor to a desired component, which itself is less thermoplastic, permits separate pieces of the membrane to be joined by welding or other thermal processes relying on the meltability of the components to achieve a bond. The invention also encompasses fabricating a reinforced ion conducting membrane by melting and mixing a non ion-conducting precursor to an ion-conducting polymer with an essentially inert polymer. The composite material is then processed to transform the non-ion conducting polymer into the ion-conducting form. The mixing of the precursor and the inert polymer may also be achieved by co-precipitating a solution of the precursor and a suspension of the inert polymer; impregnating the precursor onto the walls of the pores of a porous, essentially inert polymer; filling the pores of a porous, essentially inert polymer with a solution of comprising a non-ion conducting precursor to an ion conducting precursor and evacuating the solvent to substantially fill the pores of a porous, essentially inert polymer with the precursor; or melting the precursor, filling the pores of a porous essentially inert polymer with the melted precursor and cooling the precursor to form an essentially pore free composite membrane.
