Abstract

The prepared mesoporous SBA-15 (Santa Barbara Amorphous-15) was sulfonated and used as filler for the preparation of sulfonated polysulfone based composite electrolyte membranes. The SBA-15 and polysulfone were sulfonated using 3-mercaptopropyl trimethoxysilane and trimethylsilyl chlorosulfonate, respectively. The different weight percentages (1, 3, and 5 wt%) of sulfonated SBA-15 (SSBA-15) were used to prepare composite electrolyte membranes. Water uptake, ion exchange capacity, swelling ratio and proton conductivity of the composite membranes were studied for assessing the suitability of the electrolyte membranes for use in fuel cells. Characterization techniques such as FT-IR, XRD, SEM, TEM and Brunauer–Emmett– Teller were used to study the physico-chemical properties of the electrolyte membranes. TEM and BET analysis showed that SBA -15 retained its mesoporous structure even after sulfonation process. The prepared membranes were then tested in an in-house built single-cell fuel cell using hydrogen as fuel and oxygen as the oxidant. The fuel cell study showed that the presence of Sulfonated SBA-15 in the polymer matrix provided additional ion exchange sites and retained water for proton transfer which resulted in higher power density of 815 mW/cm2 with SPSU + 3% SSBA-15 membrane as compared with Nafion 117®.

磺化SBA-15对磺化聚砜电解质膜燃料电池性能的影响
将制备的介孔SBA-15(Santa Barbara Amorphous-15)磺化并用作制备磺化聚砜基复合电解质膜的填料。SBA-15和聚砜分别用3-巯基丙基三甲氧基硅烷和三甲基甲硅烷基氯磺酸盐磺化。使用不同重量百分比(1、3和5wt%)的磺化SBA-15(SSBA-15)制备复合电解质膜。研究了复合膜的吸水率、离子交换容量、溶胀率和质子传导性,以评估电解质膜在燃料电池中的适用性。采用FT-IR、XRD、SEM、TEM和Brunauer–Emmett–Teller等表征技术对电解质膜的理化性质进行了研究。TEM和BET分析表明,SBA-15在磺化过程中仍保持着介孔结构。然后将制备的膜在内部构建的单电池燃料电池中进行测试,使用氢气作为燃料,氧气作为氧化剂。燃料电池研究表明,聚合物基质中磺化SBA-15的存在为质子转移提供了额外的离子交换位点和保留水,与Nafion 117®相比,SPSU+3%SSBA-15膜的功率密度更高,达到815 mW/cm2。

期刊介绍: Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
