Polarization curves of membrane electrode assemblies (MEAs) containing carbon-supported platinum (Pt/C) and platinumenickel alloy (Pt 1 Ni 1 /C) as cathode catalysts were obtained for durability test as a function of time over 1100 h at constant current. Charge transfer resistance was measured using
