Kinetics Of Oxygen Electrode Reactions In Solid Oxide Cell
Original language description
La0.8Sr0.2Mn0.95O3-x (LSM) and ZrO2-Y2O3 (YSZ) are commonly used materials in high temperature solid oxide cells (SOCs). Particularly the degradation of electrode-electrolyte interface contact at an oxygen electrode has a great impact on SOCs overall performance. However, because the oxygen evolution or reduction reaction (OER/ORR) is predominantly responsible for cell activation losses. It is important to minimize these losses at the oxygen electrode. A thorough understanding of the electrochemical reactions and structural characteristics of the oxygen electrode-electrolyte interface is needed. Therefore, symmetrical LSM-YSZ-LSM cells were prepared to examine degradation mechanisms and kinetics of OER and ORR under different operating conditions. Each cell was examined by electrochemical methods and spectroscopic methods. Higher operating temperature leads to better performance; in contrast, the measured variation of oxygen concentration has a negligible effect on the cell performance.
