摘要

摘要对 La0.9Sr0.1Sc1 - xCoxO3 - δ 和 La0.9Sr0.1CoO3 - δ 两种材料及其基复合材料进行了柠檬酸盐-硝酸盐合成。复合材料是通过不同比例的单相固相混合、压制和烧结获得的。通过 X 射线相分析和稀释测量法对获得的单相和复合材料进行了研究。根据温度和气相成分的不同，采用直流四探针法研究了所得样品的导电性。此外，还对复合材料在燃料电池电极层直接分解氨的能力进行了独特的研究。

The Lanthanum-Scandate- and Lanthanum-Cobaltite-Based Composite Materials for Proton–Ceramic Electrochemical Devices

A citrate–nitrate synthesis of individual materials La_0.9Sr_0.1Sc_{1 –} _xCo_xO_{3 – δ} and La_0.9Sr_0.1CoO_{3 – δ} and their based composites is performed. Composite materials are obtained by solid-phase mixing in different percentages of individual phases, followed by pressing and sintering. The obtained individual and composite materials are explored by X-ray phase analysis and dilatometry. The electrical conductivity of the obtained samples is studied by a direct-current four-probe method depending on the temperature and the gas phase composition. Unique studies of the ability of composites to the ammonia direct decomposition directly at the electrode layer of the fuel cell are carried out.
