TECHNICAL SUMMARYThe goal of this CAREER project is to build an interdisciplinary materials research and educational program by developing a novel class of polymer electrolyte materials that will be useful for fuel cell applications. Although proton exchange membrane fuel cells (PEMFCs) are touted as efficient, reliable, and environmentally friendly energy sources, broad use of this promising technology has been limited by insufficient development of polymer electrolyte materials that can overcome the shortcomings of Nafion, the current state-of-the-art proton exchange membrane (PEM). To prepare new PEM materials that can outperform Nafion in fuel cell operation, Professor Chulsung Bae of the Department of Chemistry at University of Nevada Las Vegas will (a) develop a new synthetic strategy of PEMs that take advantages of both partially fluorinated ionomers and aromatic main-chain polymers, and (b) carry out a systematic study of the relationship between polymer structure and membrane properties. This approach will generate a sulfonic acid group that is much stronger than the aryl sulfonic acid typically found in currently available aromatic polymer ionomers, and create PEMs of a diverse range of structures that can allow better understanding of the molecular-level structure property relationships. Due to the multidisciplinary nature of fuel cell research program, students working under this CAREER project will be exposed to interactions with experts in synthetic chemistry, materials characterization, and engineering and thus be given an appreciation of the multiple aspects of a major research undertaking and the many potential paths available for graduate research and future careers. NON-TECHNICAL SUMMARYFuel cells, which convert the chemical energies stored in fuel directly into electrical energy, are expected to be a key technology for meeting energy needs in the twenty-first century. The goal of this CAREER project is to combine different fields of chemistry and materials science/engineering and create novel materials that will provide molecular-level insight into material property and play a key role in the development of commercially viable fuel cell technologies globally. Owing to the exciting and multidisciplinary nature of fuel cell research, this CAREER project will attract participants from a wide range of areas, contribute to the infrastructure and programmatic basis for research and education opportunitiese.g., graduate student training, graduate mentoring of undergraduate research assistants, classroom demonstrationsand create an academic/private industry partnership as a possible career path for students. In addition to basic research and education programs for students, building a bridge between the PI's fuel cell research and the general public's increasing concern about global climate change and gradual desire for clean alternative energy production will enhance scientific literacy, broadening the impact of this research on the society.

技术总结该职业项目的目的是通过开发一种新型的聚合物电解质材料来建立跨学科材料研究和教育计划，该材料将对燃料电池应用有用。尽管质子交换膜燃料电池（PEMFC）被吹捧为有效，可靠和环保的能源，但这种有前途的技术的广泛使用受到了无法克服NAFION（现代现有的现有Proton Exchange Meffect Membrane Membrane Membrane Membrane Membrane（PEM））的缺点的聚合物电解质材料的发展而受到限制。为了准备可以在燃料电池运行中胜过Nafion的新PEM材料，内华达大学拉斯维加斯大学化学系教授将（a）制定一种新的PEM的合成策略，这些策略具有部分荧光的离子体和芳香的主链聚合物和（b）的属性，以及（b）进行系统的结构以及范围的范围，并进行了范围的研究。这种方法将产生一个比当前可用的芳香族聚合物离子体中通常发现的芳基磺酸强得多的磺酸基，并产生具有多种结构范围的PEM，这些PEM可以更好地了解分子水平的结构性质关系。由于燃料电池研究计划的多学科性质，在此职业项目下工作的学生将与合成化学，材料表征和工程专家的互动接触，因此对重大研究工作的多个方面以及可用于研究生研究和未来职业的许多潜在途径表示赞赏。将燃料中储存在燃料中的化学能转化为电能的非技术摘要细胞有望成为满足二十一世纪能源需求的关键技术。这个职业项目的目的是结合化学和材料科学/工程的不同领域，并创建新颖的材料，这些材料将为材料特性提供分子水平的见解，并在全球商业可行的燃料电池技术的发展中发挥关键作用。由于燃料电池研究的令人兴奋和多学科的性质，该职业项目将吸引来自各个领域的参与者，为研究和教育机会的基础设施和程序基础做出贡献。除了针对学生的基础研究和教育计划外，在PI的燃料电池研究与公众对全球气候变化的关注以及对清洁替代能源生产的逐步渴望之间建立了桥梁，将增强科学素养，扩大这项研究对社会的影响。
