Abstract

Chromium poisoning phenomena were compared among three SOFC cathodes consisting of Lai0.8Sr0.2MnO3 (LSM), Lai 0.06Sri0.4Fei0.8Co0.2O3 (LSCF) and LaNii0.06Fei0.4O3 (LNF) under relatively large cathode polarization conditions. Deposition of chromium near the cathode/electrolyte interface seems to be affected only by the cathode polarization, not by the cathode materials nor the current density.
