Description |
Mixed matrix membranes based on zeolite 4A-methane sulfonic
acid (MSA)-sulfonated poly(ether ether ketone)
(SPEEK) are evaluated as a potential polymer electrolyte
membrane (PEM) for direct methanol fuel cells (DMFCs).
Ion-exchange capacity, sorption of water, and water–methanol
mixture, proton conductivity, and methanol permeability
for the mixed-matrix membranes have been extensively
investigated. The mixed-matrix membranes are also characterized
for their cross-sectional morphology, mechanical,
and thermal properties. DMFCs employing SPEEK-MSA
(20 wt.%) blend, zeolite 4A (4 wt.%)-SPEEK-MSA (20 wt.%)
mixed matrix membranes deliver peak power densities of
130 and 159 mW cm–2, respectively; while a peak power
density of only 95 mW cm–2 is obtained for the DMFC
employing pristine SPEEK membrane at 70 °C. The results
showed that these SPEEK based mixed matrix membranes
exhibit higher DMFC performance and lower methanol permeability
in comparison to Nafion-117 membrane
