Oxygen ion conductive ceramic material with low sintering temperature and preparation method thereof
The invention belongs to the field of ceramic fuel cells, and particularly relates to an oxygen ion conductive ceramic material with low sintering temperature and a preparation method thereof. The invention aims to provide a ceramic fuel cell oxygen ion conductive ceramic electrolyte with low sintering temperature and a preparation method thereof in order to solve the problems of poor sintering performance of an oxygen ion conductor cerium oxide-based electrolyte, influence of a sintering aid on the conductivity of the electrolyte and the like in the prior art. The expression of the electrolyte material is (Ce < 0.90 > Gd < 0.10 > O < 1.95 >) < 1-x > + (Fe < 2 > O < 3 >) < x >, x is the addition amount of a sintering aid Fe < 2 > O < 3 >, and x is greater than 0 and less than or equal to 0.015. The low-cost Fe2O3 is used as the sintering aid of the GDC, so that not only can the sintering temperature of the GDC be reduced by 200-300 DEG C, but also the conductivity of the GDC can be improved by 10-15%. The preparation process is simple, is easy for industrial production, and is suitable for ceramic fuel cells and related high-performance electrochemical devices thereof.
本发明属于陶瓷燃料电池领域，尤其涉及一种低烧结温度的氧离子导电陶瓷材料及其制备方法。本发明的目的是针对现有技术中氧离子导体氧化铈基电解质的烧结性能差、烧结助剂影响电解质的电导率等问题，提供了一种低烧结温度的陶瓷燃料电池氧离子导电陶瓷电解质及其制备方法。所述电解质材料表达式为(Ce0.90Gd0.10O1.95)1‑x+(Fe2O3)x，其中，x为烧结助剂Fe2O3的添加量，0＜x≤0.015。通过使用低廉的Fe2O3作为GDC的烧结助剂，不仅能使GDC的烧结温度降低200‑300℃，也能使GDC的电导率提高10‑15％。本发明制备工艺简单，易于工业化生产，适用于陶瓷燃料电池及其相关高性能电化学器件。
