  • In this work, sulfonated poly (ether ether ketone) (SPEEK) composite membranes including strontium zirconate (SrZrO3) were fabricated by the electrospinning method. Fourier-transform infrared spectroscopic analysis and X-ray diffraction analysis were used to identify the chemical structure and the crystallinity of SrZrO3 and electrospun composite membranes. The thermal stability of the pure SPEEK and SPEEK/SrZrO3 electrospun composite membranes were investigated by using thermogravimetric analysis. The physicochemical properties and proton conductivity were enhanced with the addition of different weight ratio of SrZrO3 nanofiller (2, 4 and 6 wt%) in SPEEK polymer. The optimized SPEEK/SrZrO3-4 electrospun membrane containing 4 wt% of SrZrO3 showed a high proton conductivity compared to other electrospun SPEEK/SrZrO3 composite membranes. The results indicate that electrospun composite membranes incorporating these perovskite nanofillers should be explored as potential candidates for use in proton exchange membrane fuel cells.
