Double-layer solid electrolyte proton conductor and preparation method thereof
The invention relates to a double-layer solid electrolyte proton conductor and a preparation method thereof, the double-layer solid electrolyte proton conductor is of a double-layer structure composedof a matrix part and a coating layer part, the molecular formula of the matrix part is A1-yA'yB1-zB'zO3-alpha, and the molecular formula of the coating layer part is ABO3; the preparation method comprises the steps: (1) preparing a raw material A and a raw material B, mixing and ball-milling to obtain mixed powder I; (2) pressing and calcining to prepare a calcined material I; (3) preparing a rawmaterial A, a raw material B, a raw material A' and a raw material B', mixing and ball-milling to obtain mixed powder II; (4) pressing and calcining to prepare a calcined material II; (5) carrying out compression molding on the calcined material II to prepare a matrix blank; and covering the calcined material I on a substrate blank to form a coating layer by adopting co-pressing, tape casting, spin coating, magnetron sputtering or laser deposition; and (6) sintering the double-layer blank at the temperature of 1300-1700 DEG C. The product has proton conductivity, and oxygen ion vacancies andelectron conductivity are limited at the same time.
一种双层固体电解质质子导体及其制备方法，由基体部分和涂层部分组成的双层结构，基体部分的分子式为AA′BB′O，涂层部分的分子式为ABO；制备方法为：(1)准备A原料和B原料，混合球磨获得混合粉体Ⅰ；(2)压制后煅烧制成煅烧物料Ⅰ；(3)准备A原料、B原料、A′原料和B′原料，混合球磨获得混合粉体Ⅱ；(4)压制后煅烧制成煅烧物料Ⅱ；(5)煅烧物料Ⅱ压制成型，制成基体坯料；采用共压、流延、旋涂、磁控溅射或激光沉积，将煅烧物料Ⅰ覆盖在基体坯料上形成涂层；(6)双层坯料在1300～1700℃烧结。本发明的产品具备质子导电性，同时限制住了氧离子空位及电子导电。
