## Abstract High temperature proton exchange membrane fuel cells (HTβPEMFCs) with phosphoric acid doped polybenzimidazole (PBI) membranes have gained tremendous attentions due to its attractive advantages over conventional PEMFCs such as faster electrochemical kinetics, simpler water management, hi
## Abstract Crosslinked polybenzimidazole (PBI) was synthesised __via__ free radical polymerisation between __N__βvinylimidazole and vinylbenzyl substituted PBI. The degree of crosslinking increases with increasing content of the crosslinker. The phosphoric acid doping behaviour, mechanical propert
## 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
