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
