Nanocomposite fuel cell membranes based on Nafion and acid functionalized zeolite beta nanocrystals

Research output: Journal Publications and ReviewsRGC 21 - Publication in refereed journalpeer-review

Abstract

We have prepared nanocomposite proton exchange membranes (PEMs) based on Nafion with sulfonic acid functionalized zeolite beta (AFB) as an additive. 2.5 and 5 wt% AFB composite membranes possess proton conductivity/methanol permeability (selectivity) ratios as much as 93% higher than commercial Nafion 117 at 21 °C, and 63% higher at 80 °C. These 2.5 and 5 wt% AFB composite membranes also outperform commercial Nafion 117 in direct methanol fuel cell performance evaluations. The composite membranes are characterized using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, four-electrode impedance for proton conductivity, two-compartment permeation for methanol crossover, and direct methanol fuel cell performance. © 2008 Elsevier B.V.
