...to the cathode through Nafion membranes, is a major technical problem being investigated. One solution is a methanol barrier, which can be created by screen-printing a layer of polybenzimidazole (PBI) to Nafion. Another approach is modifying the surface structure of Nafion by using electron beam (EB...

...well below the 160 C temperature used in this design that uses a PBI (polybenzimidazole polymer) PEM from PEMEAS, Germany. The high temp PEM FC solves a number of problems the MEA is CO tolerant, it eliminates a gas treatment step in the reformer, no humidification or water management issues...

...specified for thermal insulators, high-performance bearings, electrical connectors, and ablative structures. The family of imidized polymers include polyimide (PI), polyamideimide (PAI), polybenzimidazole (PBI), and polyetherimide (PEI). Chemically, all contain at least one imide linkage (carbonyl...
