제목 Lower overvoltage and high durable membrane-electrode assembly for proton exchange membrane fuel cells
초록 In membrane electrode assembly (MEA) of proton exchange membrane fuel cells (PEMFCs), Nafion ionomer is the most widely used as the electrolyte binder in the catalyst layer. A high performance MEA requires the effective5315 contact so called the three-phase boundary, high Pt catalyst utilization, sufficient proton conduction, and facile H2 and O2 reactant and water product transport. In this study, we investigated relationship of electrochemically-active surface area by tuning the properties of the dispersing medium in the ionomer. Impedance data, cyclic voltammetry, and hydrogen gas crossover and polarization curves were measured.
