NON-TECHNICAL: As a result of the recent shale gas developments, there are abundant supplies of natural gas in the U.S. and there is a critical need for a highly efficient and environmentally friendly natural gas-to-electrical energy conversion technology. Solid oxide fuel cells (SOFCs) offer great promise for such an efficient and cost-effective conversion, particularly for distributed power generation. However, the state-of-the-art SOFC nickel cermet anodes suffer from rapid performance degradation upon direct oxidation of hydrocarbon fuels. The objective of this research is to create a scientific basis for the design of novel SOFC anode materials that can maintain performance stability when directly utilizing natural gas as fuel for electricity generation. The goal of this study is to overcome SOFC anode deactivation issues, and consequently facilitate the rapid application and commercialization of SOFC technology. Widespread deployment of SOFCs will have beneficial economic and environmental impacts, making energy conversion from abundant natural gas more efficient and more environmentally benign. University students will be trained in the practice of experimental and computational material science and engineering. Graduates typically find employment in the advanced clean energy sector. Finally, the public will be educated on the benefits of fuel cell technology through various mechanisms such as interactive presentations at Science Cafes and an "Adventures in Fuel Cells" summer program that specifically targets high school students from rural areas and underrepresented groups.TECHNICAL DETAILS: In this study, ceramic oxides will be explored for overcoming the coking and sulfur poisoning problems that limit the lifetime of conventional nickel cermet SOFC anodes directly utilizing natural gas as fuel. Fundamental understanding of the ceramic oxides will guide further development of mixed ionic and electronic conducting ceramic materials for energy and engineering applications. The collaborative efforts in this research are expected to advance the fundamental understanding of high temperature oxide ion and electron conductivity and surface chemistry occurring in technologically important energy conversion devices. The focus will be on a molecular understanding of these physical phenomena and how different B-site elements in a layered perovskite oxide affect both bulk material properties such as oxide ionic and electronic conductivity and surface properties such as electrocatalytic activity and resistance to coking and sulfur poisoning. This research represents one of the first case studies for deep integration of computational predictions with experimental observations for high temperature materials in SOFCs. Students will be educated through the project to become experts in the practice of experimental and computational aspects of fuel cell technology. As a result, graduates will be well prepared to create sustainable engineering solutions to complex problems, contributing to the science and technology of energy conversion and storage.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术性：由于最近的页岩气开发，美国有大量天然气供应，并且至关重要的是高效且环保的天然气到电气对电气转换技术的迫切需求。固体氧化物燃料电池（SOFC）为这种有效且具有成本效益的转换提供了巨大的希望，尤其是对于分布式发电而言。然而，最先进的SOFC镍Cermet阳极在直接氧化碳氢化合物燃料后会迅速降解。这项研究的目的是为设计新型SOFC阳极材料的设计创建一个科学基础，这些材料可以直接利用天然气作为发电的燃料时可以保持性能稳定性。这项研究的目的是克服SOFC阳极停用问题，从而促进SOFC技术的快速应用和商业化。 SOFC的广泛部署将产生有益的经济和环境影响，从而使丰富的天然气的能源转化更有效，更环保。大学生将接受实验和计算材料科学与工程的实践培训。毕业生通常会在先进的清洁能源领域找到就业。最后，将通过各种机制（例如科学咖啡馆的互动式演示）和“燃料电池冒险冒险”的夏季计划对燃料电池技术的好处进行教育，该计划专门针对来自农村地区的高中生和代表性不足的群体的高中生。在这项研究中，将探索陶瓷氧化物，以探索陶瓷的直接毒品，以限制毒品的毒品，这些问题限制了毒品的毒品，这些问题限制了毒品的毒品，这些问题是毒品的毒品，这些问题是毒品的毒品。利用天然气作为燃料。对陶瓷氧化物的基本理解将指导混合离子和电子传导陶瓷材料的进一步开发用于能源和工程应用。预计这项研究的协作工作将提高对技术重要的能量转换设备中发生的高温氧化离子和电子电导率和表面化学反应的基本理解。重点将放在对这些物理现象的分子理解上，以及分层的钙岩氧化物中的不同B位元素如何影响诸如氧化物离子和电子电导率等散装材料的特性以及诸如电催化活性以及对焦炭和硫磺中毒的耐药性。这项研究代表了将计算预测与SOFC中高温材料的实验观察深入整合的第一个案例研究之一。将通过该项目对学生进行教育，以成为燃料电池技术实验和计算方面实践的专家。结果，毕业生将做好充分的准备，以为复杂问题创造可持续的工程解决方案，为能源转换和存储的科学和技术做出贡献。该奖项反映了NSF的法定任务，并被认为值得通过基金会的知识分子评估来获得支持，并具有更广泛的影响。
