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 a powerful new method - focused ion beam scanning electron microscopy - for fully characterizing three-dimensional electrode microstructure. 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 University of Washington and University of Michigan.

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来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或纳米结构，这对决定其性能至关重要，但目前测量电极结构的方法相当有限。该计划的目的是开发一种强大的新方法-聚焦离子束扫描电子显微镜-来全面表征三维电极的微观结构。技术细节：本研究的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。新的方法和理解将包括在新的大学课程材料和教育模块中，旨在达到广泛的年龄组。这项研究是华盛顿大学和密歇根大学的合作成果。
