FUEL CELLS – PROTON-EXCHANGE MEMBRANE FUEL CELLS | Membranes: Polybenzimidazole
2009The current research on polymer electrolytes for fuel cells is focused on the optimization of a membrane working at 120 °C and low humidity levels (<30%), which are the real operative conditions in the case of automotive applications. Among a wide variety of tested polymer systems, polybenzimidazole (PBI)-based membranes, doped with phosphoric acid,
