Novel imidazolium functionalized polysulfone (ImPS) membranes modified with zirconia (ZrO₂) were synthesized through solution casting technique. Structural, morphological, thermal and mechanical analysis of the composite membranes confirmed adhesion and property enhancement caused by ZrO₂. Water absorption investigations revealed better water absorption of the ImPS/ZrO₂ membranes with intact morphology. Maximum ion exchange capacity and ionic conductivity for the composite membranes were obtained as 2.84 mmol/g and 80.2 mS/cm (50 ^°C) which was 21% and 47% higher as compared to pure ImPS membrane. Alkaline stability of the blend membranes was increased due to strong interaction between ZrO₂ and ImPS molecules. Fuel cell performance using Pt/C catalysts exhibited OCP and power density elevation with incremental amounts of ZrO₂ in the composite membrane composition. ImPS membrane with 10% ZrO₂ recorded a highest OCP and power density of 1.04 V and 270 mW/cm² which was 35% and 39% higher than the pure ImPS. Thus, the anion exchange membranes developed by ImPS/ZrO₂ blending could be suiting well for alkaline fuel cells applications.

通过溶液流延技术合成了新型的氧化锆（ZrO ₂）改性的咪唑官能化聚砜（ImPS）膜。复合膜的结构，形态，热和机械分析证实了由ZrO ₂引起的粘附和性能增强。吸水研究表明，具有完整形态的ImPS / ZrO ₂膜具有更好的吸水率。复合膜的最大离子交换容量和离子电导率分别为2.84 mmol / g和80.2 mS / cm（50  ^° C），分别比纯ImPS膜高21％和47％。ZrO ₂之间的强相互作用增强了共混膜的碱性稳定性和ImPS分子。使用Pt / C催化剂的燃料电池性能随着复合膜组合物中ZrO _2的增加而表现出OCP和功率密度的提高。具有10％ZrO _2的ImPS膜记录的最高OCP和功率密度分别为1.04 V和270 mW / cm ²，分别比纯ImPS高35％和39％。因此，通过ImPS / ZrO ₂共混开发的阴离子交换膜可能非常适合碱性燃料电池应用。
