The sulfonated polyethersulfone (SPES) with modified TiO2 proton exchange membrane performance for the fuel cell application was reported. TiO2 nanoparticles investigated for the fuel cell performance were modified by sulfonation and surface coated using polyaniline (PANI). Fabricated membranes were analyzed in terms of water uptake, swelling ratio, methanol uptake, ion exchange capacity, chemical stability and thermal properties. Surface and structural properties of the membranes were characterized by Field Emission Scanning electron microscope (FESEM). To understand the interaction between polymer and nanoparticle, Fourier transform infrared (FTIR) and X-ray diffraction (XRD) characterization for the membranes were performed. Highest proton conductivity is 2.30 × 10−4 S/cm with SPES/STiO2–PANI (0.5%) composite membrane. The presence of modified TiO2 with amine group of PANI and sulfonic acid group were the main factors for the highest conductivity value. The composite membrane with modified TiO2 shows excellent chemical stability and thermal properties. Thus, the composite membrane incorporated with STiO2–PANI is a promising proton conducting material for fuel cell application.
