A tubular protonic ceramic fuel cell with BaCe0.7Zr0.1Y0.2O3-δ electrolyte was fabricated using the dip-coating technique. The cell showed good electrochemical performance, with output power even at a temperature as low as 200°C. Stability testing at 600°C showed that the cell's operating power density gradually stabilized over 30 hours of testing.
An anode-supported tubular protonic ceramic fuel cell with BaCe0.7Zr0.1Y0.2O3-? electrolyte is fabricated using dip-coating technique. Electrochemical performances of the cell are tested at temperatures from 600 to 200 ?C, utilizing humidified H2 (3 vol% H2O) as fuel and ambient air as oxidant. With an effective area of 2.3 cm2, the cell yields a peak power density of 465 mW cm? 2 at 600 ?C and 118 mW cm? 2 at 450 ?C. Even when the temperature is as low as 200 ?C, there is still an output power of 3 mW. Stability of the cell under 600 ?C is tested by operating the cell at a constant voltage of 0.7 V. The test lasts for 30 h during which the operating power density decreases rapidly in the first 10 h, then tend to be stable at 300 mW cm? 2.
