[Display omitted] ► The cross-linking reaction could be completed by heating at a low temperature. ► The porous PBI membranes could effectively elevate doping level. ► The CpPBI-10 could be suitable for HT-PEMFCs applications. A new approach has been proposed to obtain high-temperature proton exchan...
