    摘要： A water insoluble additive for improving the performance of an ion-exchange membrane, such as in the context of the high temperature operation of electrochemical fuel cells. The insoluble additive comprises a metal oxide cross-linked matrix having acid groups covalently attached to the matrix through linkers. In one embodiment, the metal is silicon and the cross-linked matrix is a siloxane cross-linked matrix containing silicon atoms cross-linked by multiple disiloxy bonds and having acid groups covalently attached to the silicon atoms through alkanediyl linkers.

    摘要： A significant problem in PEM fuel cell durability is in premature failure of the ion-exchange membrane and in particular by the degradation of the ion-exchange membrane by reactive hydrogen peroxide species. Such degradation can be reduced or eliminated by the presence of an additive in the anode, cathode or ion-exchange membrane. The additive may be a radical scavenger, a membrane cross-linker, a hydrogen peroxide decomposition catalyst and/or a hydrogen peroxide stabilizer. The presence of the additive in the membrane electrode assembly (MEA) may however result in reduced performance of the PEM fuel cell. Accordingly, it may be desirable to restrict the location of the additive to locations of increased susceptibility to membrane degradation such as the inlet and/or outlet regions of the MEA.

    摘要翻译： PEM燃料电池耐久性的一个重大问题是离子交换膜的过早失效，特别是通过活性过氧化氢物质降解离子交换膜。 通过在阳极，阴极或离子交换膜中存在添加剂可以降低或消除这种降解。 添加剂可以是自由基清除剂，膜交联剂，过氧化氢分解催化剂和/或过氧化氢稳定剂。 然而，添加剂在膜电极组件（MEA）中的存在可能导致PEM燃料电池的性能降低。 因此，可能需要将添加剂的位置限制在对膜降解的易感性增加的位置，例如MEA的入口和/或出口区域。

    摘要： An ion exchange membrane is prepared from a block copolymer comprising a hydrophobic polymer segment and a polar polymer segment. The ion exchange membrane is formed by placing a film layer in steam, water or an electric field at a temperature greater than about 40° C. for sufficient amount of time to develop a bicontinuous morphology. The ion exchange membrane is also formed from a film layer comprising a block copolymer and a solvent. The film layer is placed in an electric field at an elevated temperature and dried therein. The film layer is thereby converted into an ion exchange membrane with bicontinuous morphology. The ion exchange membrane prepared according to these processes exhibits improved mechanical and electrochemical properties.

    摘要： A membrane humidifier assembly includes a first flow field plate adapted to facilitate flow of a first gas thereto and a second flow field plate adapted to facilitate flow of a second gas thereto. A polymeric membrane is disposed between the first and second flow fields. The polymeric membrane is adapted to permit transfer of water between the first flow field plate and the second flow field plate. The polymeric membrane includes a polymeric substrate and a polymer layer disposed on the polymeric substrate. The polymer layer characteristically includes a first polymer having fluorinated cyclobutyl groups disposed on the polymeric substrate.
