Abstract: The properties of alkali doped poly(2,5-benzimidazole) membrane with different alkali doping level for fuel cell application is reported in this work. The alkali doping level played an important role for the ion conductivity of the membrane. The ion conductivity significantly increased with alkali doping level. The ion conductivity also increased with the temperature. The ion conductivity of the alkali doped ABPBI membrane (alkali doping level=0.37), reached to 2.3×10-2 S cm-1 at room temperature and 7.3×10-2 S cm-1 at 100 °C. The water uptake of the alkali doped ABPBI membrane was increased from 9.1% to 19.2% with increasing alkali doping level at room temperature. The alkali doped poly(2,5-benzimidazole) membrane also showed excellent ion conducting stability and thermal stability as compared with the known quaternized anion exchange membranes.
