Massgeschneiderte Wasserdampftransfermembran-Schichtstruktur

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.
