Abstract: Described herein are proton exchange membrane style electrolyzers, and methods of making same, with a polybenzimidazole (PBI) or sulfonated polybenzimidazole (s-PBI) membrane and metal catalysts on the anode and cathode, which enables both acid independent membrane resistance and lower membrane resistance with higher operating temperatures.

Abstract: A novel process for making PBI films starting from gel PBI membranes polymerized and casted in the PPA process wherein acid-imbibed gel PBIs are neutralized in a series of water baths and undergo controlled drying in association with a substrate material, yielding a PBI film without the use of organic solvents.
