Operando Optical Studies of High Temperature Energy Conversion Chemistry

Abstract

This project develops and applies operando optical techniques to characterize electrochemical oxidation mechanisms in high and inter,mediate temperature solid state fuel cells. Specifically, this work will apply complementary optical and electrochemical methods a), to study chemical heterogeneity across the surfaces of functioning fuel cell electrodes as a function of temperature, fuel identity, and applied overpotential; b) to identify mechanisms responsible for contaminant deactivation of solid oxide electrochemical cells,; c) to establish the viability of these tools to study other high temperature electrochemical cells used as electrolyzers; and d)t,o explore the carbon tolerance and reversibility of solid state fuel cells operating with proton conducting ceramic electrolytes. Wo,rk will be carried out in close collaborations with colleagues at the Naval Research Laboratory in Washington, DC.
