1. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells
University essay from Lunds universitet/Centrum för analys och syntesAbstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

2. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells
University essay from Lunds universitet/Kemiteknik (CI)Abstract : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. READ MORE
