PBI Performance Products’ PBI Film is a solution cast Polybenzimidazole (PBI) film produced from narrow range high molecular weight PBI polymer chains for application in Membrane Electrode Assemblies for Fuel Cells, Flow Batteries, and Hydrogen Pumps.
These high strength films are ideal for electrochemical cells wherein the membrane will be imbibed with Sulfuric, Phosphoric or other strong acid such that the membrane shall function in an electrochemical cell.
PBI membranes are tolerant and operate most efficiently at temperatures greater than 150C; up to about 300C. PBI membranes will not hydrolyze in steam or water.
