摘要： Graft polymeric membranes and methods for making graft polymeric membranes have one or more trifluorovinyl aromatic monomers that are radiation graft polymerized to a polymeric base film. The membranes comprise a polymeric base film to which has been graft polymerized substituted &agr;,&agr;,&bgr;-trifluorostyrene and/or &agr;,&agr;,&bgr;-trifluorovinylnaphthylene monomers, which are activated towards graft polymerization. As ion-exchange membranes, the membranes are suitable for use in electrode apparatus, including membrane electrode assemblies in, for example, fuel cells. The membranes can also be crosslinked.

摘要： A gasketed membrane electrode assembly for electrochemical fuel cells employs gasketing material at the periphery of the ion exchange membrane, rather than the membrane itself, as a gasket. The gasketing material may be formed from an elastomeric material suitable for cold bonding or bonding by heat and pressure. A nonhydrophilic thermoplastic elastomer is the preferred gasketing material. The gasketed membrane electrode assembly provides a seal between the electrically conductive separator plates that is more effective and economical than assemblies employing the membrane itself as the gasketing material. In an alternative embodiment, a gasketed membrane assembly for use in the humidification portion of a fuel cell employs gasketing material at the periphery of a water permeable membrane.
