Abstract


TriSilanolPhenyl oligomeric silsesquioxane (SO-POSS) are embedded into poly(2,5-benzimidazole) (ABPBI) matrix via in-situ synthesis and ionic liquid (IL) [BMIM]BF4 are added as proton conductor to fabricate tri-component composite membranes. The proton conductivity of ABPBI/SO-POSS/IL reaches 57 ms cm-1 at 100 °C, which is significantly higher than that of Nafion, indicating that the composite membranes could be a promising candidate for high temperature PEMFCs.
