文摘

e-PBI with higher oxidative stability was prepared by end-group protection of PBI. Homogeneous e-PBI/CeSPP composite membranes were prepared by hot-pressing. Strong hydrogen bonding network was formed in the composite membranes. Good proton conductivity was achieved at different humidity at high temperature.
