    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 and adapted to permit transfer of water from the first flow field plate to the second flow field plate. The polymeric membrane includes a polymer having perfluorocyclobutyl groups and a pendant side chain having a protogenic group.

    摘要: In one embodiment, a copolymer comprises a sulfonatable segment covalently linked to an un-sulfonatable segment through an organic linking group. The sulfonatable group segment may be sulfonated through direction sulfonation or sulfonation through a spacer molecule. In another embodiment, a copolymer comprises a sulfonated segment and an unsulfonated segment. A membrane electrode assembly and a fuel cell may be produced using the copolymer.

    摘要: A fuel cell includes a first flow field plate defining at least one flow field channel. A cathode catalyst layer is disposed over at least a portion of the first flow field plate. A polymeric ion conducting membrane is disposed over cathode catalyst layer. An anode catalyst layer is disposed over the polymeric ion conducting membrane. Finally, a second flow field plate defining at least one flow field channel is disposed over the anode catalyst layer. The polymeric ion conducting membrane extends beyond the cathode catalyst layer and the anode catalyst layer such that the fuel cell has at least one peripheral region with the polymeric catalyst layer interposed between first flow field plate and the second flow field plate without the cathode catalyst layer and the anode catalyst layer.
