## Abstract Polybenzimidazole membranes imbibed with acid are emerging as a suitable electrolyte material for highβtemperature polymer electrolyte fuel cells. The oxidative stability of polybenzimidazole has been identified as an important issue for the longβterm durability of such cells. In this p
Polybenzimidazole (PBI)/ionic liquid (IL) composite membranes were prepared from an organosoluble, fluorine-containing PBI with ionic liquid, 1-hexyl-3-methylimidazolium trifluoromethanesulfonate (HMI-Tf). PBI/HMI-Tf composite membranes with different HMI-Tf concentrations have been prepared. The io
Sulfonated carbon spheres (SCS) were employed with perfluorinated ionomers as a binder to make proton-conducting electrolyte membranes for polymer electrolyte membrane fuel cells (PEMFC). Hot-pressing produced a symmetric, thin membrane with SCS particles concentrated in the center of the membrane.
