• An electrolytic membrane for fuel cell application was fabricated by blending sulfonated poly ether sulfone octyl sulfonamide (SPESOS) with montmorillonite (MMT) clay at different proportions (1 wt.%, 3 wt.%, and 6 wt.%). The structural functionality, surface morphology, and thermal stability of the resultant composite membranes were characterized using Fourier transform infrared spectroscopy, x-ray diffraction, scanning electron microscopy, and thermogravimetric analysis. Interestingly, the thermal properties of the composite membranes were improved compared to pristine SPESOS. Furthermore, proportions as low as 0.1 wt.% in the MMT/SPESOS composite membrane showed superior proton conductivity to the SPESOS membrane. Thus, we propose the MMT/SPESOS composite membrane as a promising material for the electrolytic membrane in fuel cells at temperatures above 100°C.
