High performance low-temperature tubular protonic ceramic fuel cells based on barium cerate-zirconate electrolyte
An anode-supported tubular protonic ceramic fuel cell with BaCe0.7Zr0.1Y0.2O3-δ 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...

| description | An anode-supported tubular protonic ceramic fuel cell with BaCe0.7Zr0.1Y0.2O3-δ 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. |
