Abstract

We already clarified that chromium deposition near the cathode/electrolyte interface was predominantly affected by the cathode polarization and the chromium deposition occurred not only on the cathode materials (LSM, LSCF etc.) but also on the electrolyte material, which seems to be involved in the electrode reaction sites. In this study, influence of cathode polarization change on the distribution of the deposited chromium was investigated by using LSM cathode. Microstructure at the cathode/electrolyte interface seems to change by cathode polarization and the microscopic distribution of the deposited chromium can be affected by the change in the microstructure.
