Collaborative Research: Three-Dimensional Mapping of Solid Oxide Fuel Cell Electrodes: Processing, Structure, Stability, and Electrochemistry

非技术描述：燃料电池正在积极发展，因为它们可以提供一种更有效和无污染的方法将化学能转化为电能。 虽然燃料电池电极通常具有复杂的微米或纳米结构，这在确定其性能方面至关重要，但目前用于测量电极结构的方法非常有限。 拟议项目的目的是开发分析和模拟工具，以表征三维电极微观结构，并了解微观结构的演变和由此产生的电化学性能。 技术规格：本研究的一个主要目的是充分了解电极加工，结构，性能和性能之间的关系。 这将最终允许设计更高性能和更稳定的电极微结构，以及提供实现这些结构所需的处理信息。 新的方法和理解将被纳入新的大学课程材料和教育模块，以覆盖广泛的年龄组。这项研究是与西北大学和华盛顿大学的合作成果。

NON-TECHNICAL DESCRIPTION: Fuel cells are being actively developed because they can provide a more efficient and pollution-free method for converting chemical energy to electricity. While fuel cell electrodes typically have a complex micro- or nano-structure that is critically important in determining their performance, current methods for measuring electrode structure are quite limited. The aim of the proposed project is to develop analysis and simulation tools to characterize the three-dimensional electrode microstructure and to understand microstructural evolution and the resulting electrochemical performance. TECHNICAL DETAILS: A main aim of this research is to fully understand the relationships between electrode processing, structure, properties, and performance. This will ultimately allow design of higher performance and more stable electrode microstructures, as well as providing processing information needed to achieve these structures. The new methods and understanding will be included in new university course materials and in educational modules designed to reach a broad spectrum of age groups. This research is a collaborative effort with Northwestern University and University of Washington.
