NON-TECHNICAL DESCRIPTION: Fuel cells potentially provide a more efficient and pollution-free method for converting chemical energy to electricity. The performance of fuel cell electrodes depends strongly on the details of the electrodes' micro- or nano-structure. However, traditional methods for measuring material morphology (e.g. electron microscopy) are limited to two dimensions. The aim of the proposed project is to develop a powerful new method - focused ion beam scanning electron microscopy - for fully characterizing electrode microstructure in three dimensions. The new information available by this method will allow workers to connect performance and structure directly, enabling further advances in the technology. These new methods will be included in new university course materials and in educational modules designed to reach a broad spectrum of age groups. 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 methods developed are also of general interest to the engineering community. New course material based on this work will be integrated into the PI's existing courses on fuel cells at the University of Washington (UW). The 3D images will also facilitate demonstration of scientific principles to youths in unprecedented detail, and will become part of UW's yearly outreach to local area schools. This research is a collaborative effort with Northwestern University and the University of Michigan.

非技术描述：燃料电池可能提供了一种将化学能转换为电能的更有效和无污染的方法。 燃料电池电极的性能在很大程度上取决于电极微或纳米结构的细节。 但是，测量材料形态的传统方法（例如电子显微镜）限于两个维度。 拟议项目的目的是开发一种强大的新方法 - 聚焦的离子束扫描电子显微镜 - 以在三个维度中充分表征电极显微结构。 这种方法可获得的新信息将使工人能够直接连接性能和结构，从而在技术中进一步进步。这些新方法将包括在新的大学课程材料和旨在达到各种年龄段的教育模块中。 技术细节：这项研究的主要目的是充分了解电极处理，结构，属性和性能之间的关系。 这最终将允许设计更高的性能和更稳定的电极微观结构，并提供实现这些结构所需的处理信息。 所开发的方法也引起了工程界的普遍兴趣。 基于这项工作的新课程材料将集成到华盛顿大学（UW）的PI现有课程中。 3D图像还将以前所未有的细节为年轻人促进科学原则，并将成为西澳大学年度向当地学校的宣传的一部分。这项研究是与西北大学和密歇根大学的合作努力。
