Abstract

This paper evaluates cell performances and electrode reaction of an electrolyte supported type cell using 15mol% Y-doped BaZrO3 perovskite type proton conductors. BaZrO3 based proton conductors show high proton conductivity and chemical stability in IT-SOFC operating atmospheres. But, because of low sintering properties, there is little knowledge about electrolyte performance, e.g., open circuit voltage, electrode over potential. Through SOFC generation test, it is confirmed that cell performance of the cell is determined by electrode over potential. Electrode over potential is significantly higher than similar configuration cell using BaCeO3 based proton conductors. Those results suggests that study of differences in electrode reaction between BaCeO3 based proton conductors and BaZrO3 based proton conductors will be necessary.
