CAREER: An Integrated Research and Education on Functionally Graded Solid Oxide Fuel Cells: Modeling and Experiments

摘要本研究涉及固体氧化物燃料电池的电化学性能和力学性能。改善SOFC性能的一个有希望的方法是使用功能梯度电极而不是纯单片或复合电极。该项目将利用内聚区模型、相互作用积分以及随机裂缝建模和敏感性分析，对功能梯度SOFCs进行三维瞬态热裂缝分析。裂缝建模将通过SOFC实验进行验证。该项目将以这样一种方式进行，即燃料电池研究的兴奋将与从高中到研究生院的学生以及康涅狄格大学和全世界的燃料电池研究人员分享。研究成果将用于两个拓展项目，如达芬奇工作室和工程2000，这是现有的校园暑期充实计划，新英格兰初中和高中数学科学教师和高中生分别。

CAREER: An Integrated Research and Education on Functionally Graded Solid Oxide Fuel Cells: Modeling and ExperimentsAbstractThis research is concerned with electrochemical and mechanical performances of solid oxide fuel cells. One promising approach for improving SOFC performance is the use of functionally graded electrodes rather than purely monolithic or composite electrodes. This program will address three-dimensional transient thermal fracture analysis of functionally graded SOFCs using cohesive zone models and interaction integrals along with stochastic fracture modeling and sensitivity analysis. Fracture modeling will be validated with SOFC experiments. The program will be carried out in such a manner that the excitement of fuel cell research will be shared with students from high school through graduate school, and fuel cell researchers at the University of Connecticut and throughout the world. Research findings will be utilized in two outreach programs, e.g. the da Vinci Workshop and Engineering 2000, which are existing on-campus summer enrichment programs for New England middle and high school math-science teachers and high school students, respectively.
