Abstract

Physically reinforced short-side-chain perfluorinated sulfonic acid electrolyte membranes were fabricated by annealing and using a porous support. Five types of solution-cast membranes were produced from commercial perfluorinated ionomers (3M and Aquivion (AQ)) with different equivalent weights, annealed at different temperatures, and characterized in terms of ion conductivity, water uptake, and in-plane/through-plane swelling, while the effect of annealing on physical structure of membranes was evaluated by small-angle X-ray scattering and dynamic mechanical analysis. To create a reinforced composite membrane (RCM), we impregnated a polytetrafluoroethylene porous support with 3M 729 and AQ 720 electrolytes exhibiting excellent proton conductivity and water uptake. The electrolyte impregnation stability for the porous support was evaluated using a solvent resistance test, and the best performance was observed for the 3M 729 RCM annealed at 200 °C. Both annealed and nonannealed 3M 729 RCMs were used to produce membrane electrode assemblies, the durability of which was evaluated by open-circuit voltage combined wet-dry cycling tests. The nonannealed 3M 729 RCM survived 5800 cycles, while the 3M 729 RCM annealed at 200 °C survived 16 600 cycles and thus exhibited improved mechanical durability.

摘要

通过退火和使用多孔支撑体制备了物理增强的短侧链全氟磺酸电解质膜。由具有不同当量重量的商用全氟离子聚合物（3M和阿奎维昂（AQ））制备了五种溶液浇铸膜，在不同温度下进行退火，并对其离子电导率、吸水率和面内/面外溶胀进行了表征，同时通过小角X射线散射和动态力学分析评估了退火对膜物理结构的影响。为了制备增强复合膜（RCM），我们用具有优异质子传导率和吸水率的3M 729和AQ 720电解质浸渍了聚四氟乙烯多孔支撑体。使用耐溶剂性测试评估了多孔支撑体的电解质浸渍稳定性，观察到在200℃退火的3M 729 RCM具有最佳性能。退火和未退火的3M 729 RCM均用于制备膜电极组件，通过开路电压联合干湿循环测试评估其耐久性。未退火的3M 729 RCM经受了5800次循环，而在200℃退火的3M 729 RCM经受了16600次循环，因此表现出改善的机械耐久性。
