## Abstract Membranes based on poly[2,2′‐(p‐oxydiphenylene)‐5,5′‐bibenzimidazole] (OPBI) and their sulphonated derivatives (SOPBI) were prepared and first investigated for high temperature proton exchange membrane fuel cells. OPBI and SOPBI membranes with good chemical stability were prepared by ca
