Understanding the activity and stability of electrode materials targeted for clean energy applications through diagnostic impedance measurements

该研究计划的重点是针对电化学能源系统的先进材料的基础研究。特别是金属/金属合金纳米颗粒，先进的碳材料以及金属纳米颗粒与这些碳的组合。这些材料是许多电化学能源技术的核心，包括燃料电池，电解槽和电化学/超级电容器。这些技术有可能在能源领域得到更广泛的应用，前提是可以提高材料的性能成本比，并提高其耐用性。除了材料本身的改进之外，还需要改进能够容易地评估电极健康状态的多个指标的诊断工具。

This research program focuses on fundamental studies of advanced materials targeted for electrochemical energy systems. Specifically metal/metal-alloy nanoparticles, advanced carbon materials as well as combinations of metals nanoparticles with these carbons. Such materials are at the heart of numerous electrochemical energy technologies, including fuel cells, electrolyzers and electrochemical/super capacitors. These technologies have the potential to be more widely deployed in the energy landscape provided that improvements can be made in the performance-to-cost ratio of the materials, and also in their durability. In addition to improvements in the materials themselves, improvements are needed in diagnostic tools that can readily assess multiple indicators of the electrode state-of-health.
