文摘
- •
A bi-layer electrolyte, cathode-YSZ-8CYSZ (ceria doped YSZ) –anode, was fabricated for anode supported cells with embedded Pt probes.
- •
Internal pO2 in the electrolyte close to the anode side was significantly depressed as a result of electronic conduction in the 8CYSZ.
- •
No electrochemical degradation was observed during negative voltage operation.
- •
A bi-layer cell is effective in preventing anode/electrolyte delamination as well as maintaining open circuit voltage.
