Fabrication and performance evaluation of new nanocomposite membranes based on sulfonated poly(phthalazinone ether ketone) for PEM fuel cells.

The purpose of this work is to enhance the proton conductivity and fuel cell performance of sulfonated poly(phthalazinone ether ketone) (SPPEK) as a proton exchange membrane through the application of SrTiO perovskite nanoparticles. Nanocomposite membranes based on SPPEK and SrTiO perovskite nanoparticles were prepared a casting method. The highest proton conductivity of nanocomposite membranes obtained was 120 mS cm at 90 °C and 95% RH.
