In-Situ Optical Studies of Oxidation/Reduction Kinetics on SOFC Cermet Anodes

摘要

Despite our advances in applying vibrational Raman scattering to questions about electrochemical oxidation mechanisms in SOFCs, the experimental assembly developed by our research program suffers from two limitations: spatial resolution and assembly sensitivity. We have continued to advance our ability to use in situ vibrational Raman scattering to study chemistry occurring across SOFC anodes. Doing so will involve designing next generation, optically-accessible SOFC rigs that can be supported on a computer-controlled, 2-dimensional xy stage. With support from the Murdock Charitable Trust we will soon be enhancing our capabilities to include new Raman microscope using ultraviolet, 244 nm excitation.
