In this research, the proton exchange membrane (PEM) composed of sulfonated poly(ether ether ketone) (SPEEK) as a matrix material and reduced graphene oxides nanoribbons (rGONR) wrapped titanium dioxide (TiO₂) microspheres as filler is fabricated using the simple solution casting method. The incorporation of the of rGONR (optimized amount) wrapped TiO₂ ([email protected]₂) nanofiller, acts as a novel self-humidifying/water trapping nanoshell and regulates the presence of (SO₃⁻)_n ionic clusters in SPEEK matrix to build a better network without losing the motion of protons. The network formation dramatically stimulated the proton transport of the SPEEK/[email protected]₂ (SPTC) nanohybrid PEM and improved it up to 188% (0.62 S cm⁻¹ for SPEEK to 1.79 S cm⁻¹ for SPTC) at 100 °C. The activation energy (E_a) and diffusion coefficient (D_σ) for SPTC membrane are found to be 9.15 kJ mol⁻¹ and 4.92 × 10⁻⁸ m² s⁻¹, respectively, which is in an excellent agreement to ensure better proton conductivity and lower ionic resistance.
