GOALI: Electrode Interface Stresses, Degradation, and Failure

为了使固体氧化物燃料电池（sofc）对电力的生产和分配产生重大影响，必须克服商业化的主要障碍。电极-电解质界面的耐用性和可靠性已被认为是sofc的弱点。因此，该奖项的研究目标包括以下内容：a)确定电极界面退化和失效的基于基本应力、基于材料和基于环境的原因；b)开发适合于优化暴露于热瞬态的电极界面的高保真有限元模型。这项工作将包括一系列确定材料特性和阐明失效机制的实验。实验结果也将用于开发和验证优化电极界面的数值模型。俄亥俄州立大学（OSU）的研究团队将与NexTech材料有限公司（NTM）的科学家和工程师密切合作。通过控制实验和具有生产准备材料和设备的现实模型，大学-工业团队旨在提供对电极界面失效问题的新的科学理解，并最终提供更可行的商业SOFC产品。俄勒冈州立大学和NTM的团队成员和密切合作伙伴将从各自同行的设施和知识中受益。该小组还将共同努力，向哥伦布地区的中学生和高中生传播有关能源生产和利用的一般信息。为了让学生更广泛地了解能源问题，这项工作将采取以下形式：参观教室、提供适合学生年龄的课程材料和作业，以及提供燃料电池示范工具包。

In order for solid oxide fuel cells (SOFCs) to have a significant impact on the production and distribution of electricity, key barriers to commercialization must be overcome. The durability and reliability of electrode-electrolyte interfaces has been identified as a weak point for SOFCs. Thus the research objectives of this award include the following: a) identification of fundamental stress-based, materials-based, and environment-based reasons for degradation and failure of electrode interfaces and b) development of high fidelity finite element models appropriate for optimizing electrode interfaces exposed to thermal transients. The work will include a range of experiments for determining materials properties and for elucidating failure mechanisms. The experimental results will also be used for developing and validating the numerical models designed to optimize electrode interfaces. The research team at The Ohio State University (OSU) will work closely with scientists and engineers at NexTech Materials, Ltd (NTM). Through controlled experiments and realistic models with production-ready materials and devices, the university-industry team aims to deliver both new scientific understanding of electrode interface failure issues and ultimately more viable commercial SOFC products. The team members and close associates from both OSU and NTM will benefit from having access to the facilities and knowledge of their respective counterparts. The Team will also work together to disseminate general information about energy production and use to middle and high school students in the Columbus area. This effort to provide broader understanding of energy issues will take the form of visits to classrooms, age-appropriate curriculum materials and assignments, and fuel cell demonstration kits.
