Proton conductor ceramic electrolyte and preparation method thereof
The structural composition of the proton conductor ceramic electrolyte is Ba1 + xZryCe1-y-z-uYzYbuO3-delta, in the formula, x is larger than or equal to 0.015 and smaller than or equal to 0.045, y is larger than or equal to 0.1 and smaller than or equal to 0.5, z is larger than or equal to 0.1 and smaller than or equal to 0.2, u is larger than or equal to 0 and smaller than or equal to 0.1, and delta represents non-stoichiometric oxygen. The preparation method adopts an EDTA-CA (Ethylene Diamine Tetraacetic Acid-Carbonic Acid) method or a solid phase method, the EDTA-CA method comprises the following steps: respectively adding raw material powder into water for dissolving, then adding EDTA and CA, uniformly mixing, adjusting the pH value, and continuously stirring at 80-90 DEG C until black transparent gel is obtained; pretreating the black transparent gel at 250-350 DEG C for 12-24 hours, and roasting to obtain electrolyte powder; and the latter is obtained by adding the raw material powder into a ball milling tank, then adding absolute ethyl alcohol, carrying out ball milling and uniform mixing in advance, drying and then roasting. The method can improve the sintering activity of the electrolyte and promote the growth of electrolyte grains.
一种质子导体陶瓷电解质及其制备方法，所述质子导体陶瓷电解质的结构组成为：Ba1+xZryCe1‑y‑z‑uYzYbuO3‑δ，式中，0.015≤x≤0.045，0.1≤y≤0.5，0.1≤z≤0.2，0≤u≤0.1，δ表示非化学计量氧。制备方法采用EDTA‑CA法或固相法，前者是将原料粉体分别加入水中溶解，再加入EDTA和CA，混匀后调节pH值，在80～90℃下持续搅拌，直至得到黑色透明凝胶；将黑色透明凝胶于250～350℃下预处理12‑24h后，焙烧获得电解质粉体；后者是将原料粉体加入球磨罐中，再加入无水乙醇，预先球磨混匀，烘干后焙烧获得。该方法可提高电解质的烧结活性，促进电解质晶粒生长。
