Research Abstract

Chromium poisoning phenomena were studied for different SOFC cathodes and it was found that the deposition of chromium was affected only by the cathode polarization(i. e. decrease in oxygen activity), not by the current density. No difference was found among LSM, LSCF and LNF about the amount of chromium deposition at the cathode/electrolyte interface.
