摘要: Abstract In this work, perovskite-type SrCeO 3 nanoparticles were used for improving the properties of high temperature polybenzimodazole (PBI) based proton exchange membranes. Novel conducting membrane nanocomposites prepared using different amounts nanopowders dispersed into by solution casting method.The nanocomposite membranes studied AC impedance spectroscopy, scanning electron microscopy coupled with energy dispersive X-ray and thermo gravimetric analysis. The showed a higher acid uptake, conductivity thermal stability compared pure PBI highest uptake (190%) (0.105 S/cm at 180 °C 0% RH) observed phosphoric acide-dopped containing 8 wt% (PSC ). PSC tested in fuel cell polarization power curves obtained temperatures. 0.44 W/cm 2 density 0.88 A / cm current 0.5 V 180 °C. result from our studies shows enhanced potential as cells.
