고분자 전해질 연료전지용 술폰화된 폴리(아릴렌 이써 설폰)/ SPVdF-co-HFP 브렌딩 멤브레인의 제조 및 특성 분석 = Preparation and Characterization of SPAES/SPVdF-co-HFP Blending Membranes for Polymer Electrolyte Membrane Fuel Cells

다국어 초록 (Multilingual Abstract)

In this work, preparation and characterizations of hybrid membranes containing sulfonated poly(arylene ether sulfone) (SPES) and sulfonated poly(vinylidene fluoride-co-hexafluoropropylene) (SPVdF-co-HFP) (20, 30 or 40 wt%) were carried out. The structure of hybrid membranes was confirmed using X-ray diffraction (XRD) analysis and the Fourier transform infrared (FT-IR) spectroscopy. The prepared SPAES/SPVdF-30 membrane exhibits higher ionic conductivity of 68.9 mS/cm at 90℃ and 100% RH. Besides, the other studies showed that the hybrid membrane has good oxidation stability, thermal stability, and mechanical stability. Thus, we believe that the prepared hybrid membrane is suitable for the development of membranes for fuel cell applications.
