| 英文摘要 | Solid oxide electrolysis cell is a highly promising technology for CO2 electrolysis and has attracted wide attention. But the durability is insufficient by known designed structure of solid oxide electrolysis cell due to structure damage. In this work, a new flat-tube solid oxide electrolysis cell (SOEC) based on double-sided air electrodes with mechanically-strong redox properties and larger active area was proposed and applied to electrolysis of CO2, and its electrochemical performance and long-term durability were investigated. The results showed that the charging current density reaches -600 mA/cm(2) at 1.5 V and 750 degrees C under H-2/CO2 atmosphere. The CO2 conversion rate achieves 47.4% with energy conversation efficiency of 91.4% at the electrolysis voltage of 1.305 V under the charging current density of -400 mA/cm(2), corresponding to 210 mL/min of CO production rate. This new cell architecture for CO2 electrolysis was stable at the current density of -300 mA/cm(2) for 1910 h at 750 degrees C with a degradation rate of 4.89%/kh. The new flat-tube solid oxide electrolysis cell is capable to conduct CO2 electrolysis with high efficiency and long-term stability. |
