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 SrTiO₃ perovskite nanoparticles. Nanocomposite membranes based on SPPEK and SrTiO₃ perovskite nanoparticles were prepared via a casting method. The highest proton conductivity of nanocomposite membranes obtained was 120 mS cm⁻¹ at 90 °C and 95% RH. These enhancements could be related to the hygroscopic structure of SrTiO₃ perovskite nanoparticles and the formation of hydrogen bonds between nanoparticles and water molecules. The satisfactory power density, 0.41 W cm⁻² at 0.5 V and 85 °C, of the nanocomposite membrane (5 wt% content of nanoparticles) confirms their potential for application in the PEM fuel cells.

基于磺化聚酞嗪酮醚酮的新型 PEM 燃料电池纳米复合膜的制备与性能评估

这项工作的目的是通过应用 SrTiO ₃钙钛矿纳米粒子来提高作为质子交换膜的磺化聚酞嗪酮醚酮 (SPPEK) 的质子传导性和燃料电池性能。基于SPPEK和SrTiO ₃钙钛矿纳米粒子的纳米复合膜通过浇铸法制备。在 90 °C 和 95% RH 下，获得的纳米复合膜的最高质子电导率为 120 mS cm ^{-1 。}这些增强可能与 SrTiO ₃钙钛矿纳米粒子的吸湿结构以及纳米粒子和水分子之间氢键的形成有关。令人满意的功率密度，0.41 W cm ^-2在 0.5 V 和 85 °C 下，纳米复合膜（5 wt% 的纳米颗粒含量）证实了它们在 PEM 燃料电池中的应用潜力。
