| 摘 要： | 为建立可再生能源与化学储能之间的联系,利用商业化固体氧化物电解池对二氧化碳和水蒸气进行原位还原,探讨该过程的可行性以及未来规模化集成的前景。组装了2单元固体氧化物电解池堆,分别测试其在“共电解”条件下的I-V曲线、电化学阻抗谱(electrochemical impedaance sperctroscopy,EIS)、V-t曲线,并对电解后的微结构进行表征。结果显示:商业化电解池表现出优越的电化学性能与结构稳定性,并具有进一步规模化的潜力。同时密封材料、连接体和集流体的其他关键材料也具备较好的耐久性与一致性。

| Abstract: | To establish a link between renewable energy and chemical energy,in situ reduction studies of carbon dioxide and water vapor were conducted through commercial solid oxide electrolytic cells,in an attempt to discuss the feasibility of this process and the prospect of scale integration in the future.A two-unit solid oxide electrolytic cell stack was assembled,and its I-V curve,EIS,and V-t curve under"co-electrolysis"conditions were tested,and the microstructure was characterized after the end of electrolysis.The results show that the commercial electrolytic cell had superior electrochemical performance and structural stability,and had the potential for further scale-up.At the same time,the successful test of the two-cell electrolytic cell stack also show that the sealing material,connecting body and other key materials of the current collector also had good durability and consistency. |
