Abstract

In this work, proton exchange membranes based on polybenzimidazole (PBI) with incorporation of acidic Fe3O4@SiO2@RF (resorcinol–formaldehyde)–SO3H nanoparticles are produced. The effects of the core@double-shell nanoparticles on the fuel cell performance of the PBI membrane are examined. The obtained results demonstrate that the proton conductivity of the PBI-Fe3O4@SiO2@RF–SO3H nanocomposite membranes increases. The interactions of Fe3O4@SiO2@RF–SO3H nanoparticles in the PBI matrix (which contains phosphoric acid) have strong effects on proton conductivity. The best proton conductivity of 170 mS cm−1 is obtained in the nanocomposite membrane at 180 °C. The potential for the use of these nanocomposite membranes with improved fuel cell performance in high-temperature applications is confirmed.
基于聚苯并咪唑的新型纳米复合膜提高了燃料电池的高温性能
在这项工作中,基于聚苯并咪唑(PBI)的质子交换膜结合了酸性Fe3O4@SiO2@产生了RF(间苯二酚-甲醛)-SO3H纳米颗粒。core@double-shell考察了纳米粒子对PBI膜燃料电池性能的影响。所得结果表明PBI-Fe3O4@SiO2@RF–SO3H纳米复合膜增加。Fe3O4@SiO2@PBI基质(含有磷酸)中的RF–SO3H纳米颗粒对质子电导率有很强的影响。在180°C下,纳米复合膜获得了170 mS cm−1的最佳质子电导率。这些具有改进的燃料电池性能的纳米复合膜在高温应用中的应用潜力得到了证实。
