Abstract

We describe a polymer electrolyte fuel cell (PMFC) with an extremely high durability (single cell test: >400,000 cycling) together with a high power density (252 mW/cm2) at high temperature (120°C) under a non-humid atmosphere. Such a high performance PMFC development opens the door for the nextgeneration PEFC for "real world" use. This is achieved by using a membrane electrode assembly (MEA) with poly(vinylphosphonic acid)-doped poly[2,2'-(2,6-pyridine)-5,5'-bibenzimidazole] (PyPBI)-wrapped carbon nanotube/Pt nanoparticles and poly[2,2'- (2,6-phenyl)-5,5'-bibenzimidazole] (PBI) for both the anode and cathode catalysts and an electrolyte membrane material, respectively.
