Durability tests of BCY-BZY electrolyte fuel cells under severe operating conditions
Source abstract
Abstract
Abstract Anode supported BCY (anode side) - BZY (cathode side) cells were fabricated and their durability was investigated under constant current tests. The cells remained stable under the severe operating conditions of negative cell voltage and high air utilization. This is because the BZY layer at the cathode side provided local electronic conduction, which prevented electrolyte/electrode delamination under negative voltage, as well as chemical stability against water vapor attack under high air utilization conditions. No significant changes in composition or phase were observed in the cells following the tests. These results are contrary to those reported for a single layer BCY cell. The present work suggests that a protonic ceramic fuel cell fabricated with BZY+LSCF cathode, BZY/BCY electrolyte, and Ni + BCY anode provides superior durability under severe operating conditions.
