Disclosed herein is co-ABPBI membranes comprising co-ABPBI of formula (I), Invention discloses a sol gel process for the synthesis of membranes comprising co-ABPBI of formula (I). 

Co-ABPBI membranes and process for the preparation thereof

Asymmetric membranes in hollow fiber and flat sheet forms are disclosed herewith. The process of preparation of the membranes is further disclosed. The membranes are characterized and find application in the separation of gases and solutes.

Asymmetric membranes based on BuPBI

Blend membranes based on polybenzimidazole (PBI) and polymeric ionic liquids (PILs), wherein said PBI and aliphatic PIL blend enhances Hand OHions conductivity, are provided. In particular, the blend membrane includes polybenzimidazole (PBI) and poly (diallyl dimethyl ammonium) trifluoromethane sulphonate with enhanced proton and hydroxyl ion conductivity.

Blend membranes based on polybenzimidazole (PBI) and polymeric ionic liquids (PILs) and a process for the preparation thereof

PBI-based MEAs for high temperature Polymer Electrolyte Membrane Fuel Cell (PEMFC) were prepared by direct hot pressing of catalyst layer on Teflon sheets on to both sides of phosphoric acid doped PBI membrane (decal transfer). These MEAs show two times higher performance compared to the MEAs prepared by normal brush coating method on GDL at an operating temperature of 160&#xb0; C.
