Supramolecular Fuel Cell Membranes
نویسندگان
چکیده
The currently available PEMs are suitable for use at maximum 80C because of the requirement of the presence of water for proton conductivity. However, for emerging applications, a fuel cell operating at temperatures as high as 120 C is required. This can possibly be achieved by creating novel PEMs. Supramolecular polymers are being investigated extensively and may be conjugated with heteropolyacids (HPAs) to prepare high performance PEMs. Metal coordinated polymers, such as: ruthenium or zinc bipyridine polybenzimidazole (PBI) will be synthesized during this project. Self assembled supramolecular structures are formed by the interaction of metal (Ru or Zn) and the nitrogen heterocycle from bipyridine PBI [1]. In addition, hydrophilic – hydrophobic blocks of polymer backbones also create supramolecular interactions, resulting in bi-directional proton conductivity.
