## 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) is the material of choice to fabricate proton exchange membranes for high temperature PEMFCs. Among the most recent trends in the design of PBI polymers, we recall the introduction of oxygen atoms in the polymer backbone. In fact, the presence of ether groups improves the pol
