摘要：
In this study, La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) oxygen electrode as well as Gd0.1Ce0.9O2-delta (GDC) barrier layer was employed by the screen printing process for both fuel cell and H2O/CO2 co-electrolysis operations. After initial performance evaluation of the cell under SOFC mode, electrochemical measurements of the cell were carried out at 700-800 degrees C for co-electrolysis mode with 45 % H2O, 45% CO2 and 10% H-2 as feed gas. Further, the long-term durability of the cell was examined at a constant current of 0.4 A*cm(-2) for over 200 h. It showed that cell voltage held at a steady value after experiencing initial significant fluctuations.
