Fuel cell electrolyte diaphragm with low sintering temperature and preparation method thereof
The invention belongs to the field of solid oxide fuel cells, and particularly relates to a fuel cell electrolyte diaphragm with low sintering temperature and a preparation method thereof. The invention aims to provide a fuel cell electrolyte diaphragm with low sintering temperature and a preparation method thereof in order to solve the problems that the sintering performance of a zirconia-based electrolyte is poor and the conductivity of the electrolyte is influenced by a sintering aid in the prior art. The expression of the electrolyte material is (SC<2>O<3>)<0.1>(CeO<2>)<0.01>(ZrO<2>)<0.89>)<1-x>+(ZnO), x is the addition amount of the sintering aid ZnO, and x is greater than 0 and less than or equal to 0.05. The low-cost ZnO is used as the sintering aid of the SSZ, so that not only can the sintering temperature of the SSZ be reduced by 150-250 DEG C, but also the conductivity of the SSZ can be improved by 10-25%. The preparation process is simple, is easy for industrial production, and is suitable for solid oxide fuel cells and related high-performance electrochemical devices thereof.
本发明属于固体氧化物燃料电池领域，尤其涉及一种低烧结温度的燃料电池电解质隔膜及其制备方法。本发明的目的是针对现有技术中氧化锆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燃料电池电解质隔膜及其制备方法。所述电解质材料表达式为((SC2O3)0.1(CeO2)0.01(ZrO2)0.89)1‑x+(ZnO)x，其中，x为烧结助剂ZnO的添加量，0＜x≤0.05。通过使用低廉的ZnO作为SSZ的烧结助剂，不仅能使SSZ的烧结温度降低150‑250oC，也能使SSZ的电导率提高10‑25%。本发明制备工艺简单，易于工业化生产，适用于固体氧化物燃料电池及其相关高性能电化学器件。
