中文摘要:
      开发在中、低温下具有高电导率的电解质材料是未来发展低成本固体氧化物燃料电池(SOFC)的重要方向。掺杂氧化铈(DCO)在500~700 ℃时,具有良好的导电性能,其离子电导率远远高于同温度下氧化钇稳定的氧化锆(YSZ)电解质材料,因此其成为中温SOFC电解质材料应用与研究的重点。但DCO在还原气氛下Ce4+部分还原为Ce3+,会引起电子电导增加、制造成本提高、开路电压降低等问题。针对这些问题,大量研究通过稀土或碱金属掺杂、电解质复合进行了探索,发现掺杂和多相电解质复合有助于提高DCO的离子电导率和稳定性。在概述锆基固体电解质、Bi2O3基电解质、LaGaO3基氧化物、CeO2基氧化物等SOFC电解质的基础上,重点综述了单掺杂、双掺杂和多掺杂的氧化铈电解质,同时综述了掺杂氧化铈-碳酸盐复合电解质和两种电解质复合的电解质材料的研究进展。另外,介绍了流延、丝网印刷、浆料涂覆、电泳沉积、喷雾热解、溅射、大气等离子喷涂、激光脉冲沉积等制膜方法,在铈基电解质膜制备方面的应用。最后,对铈基电解质的发展前景和方向进行了展望。
英文摘要:
      The development of electrolyte materials with high conductivity at low and medium temperatures is an important direction for the future development of low-cost solid oxide fuel cells (SOFC). Doped cerium oxide (DCO) has good electrical conductivity at 500~700 ℃, and its ionic conductivity is much higher than that of yttria-stabilized zirconia (YSZ) electrolyte materials at the same temperature, so it becomes the focus in application and research of medium temperature SOFC electrolyte material. However, Ce4+ in DCO is easy to be partially reduced to Ce3+ in reducing atmosphere, increasing electronic conductivity and manufacturing costs, and reducing open circuit voltage. Therefore, many studies have been conducted on rare earth elements and alkaline earth metals doped cerium oxide electrolytes and composite electrolytes to overcome these problems, and it has been found that the two-phase composite electrolyte is conductive to improving the ionic conductivity and stability of DCO. Based on the overview of zirconium-based solid electrolytes, Bi2O3-based electrolytes, LaGaO3-based oxides, CeO2-based oxides and other SOFC electrolytes, the single doped, double doped, and multi-doped cerium oxide electrolytes were summarized. The research progress of doped cerium oxide-carbonate composite electrolyte and two kinds of electrolyte composite electrolyte materials was also reviewed. In addition, the application of film-forming methods such as casting, screen printing, slurry coating, electrophoresis deposition, spray pyrolysis, sputtering, atmospheric plasma spraying, and laser pulse deposition was introduced in the preparation of cerium-based electrolyte film formation. In the end, the research direction of cerium base electrolyte was prospected.
