Synthesis and Conductivity of CaZr0.9Y0.1O3–δ Electrolyte Films on Supporting Composite Electrodes

Resumo

Conditions of the chemical solution deposition of CaZrO₃-based electrolyte films on supporting composite electrodes are studied. The films are formed on the composites of CaZrO3 with metal oxides СuO, Fe₂O₃, and NiO. The morphology and the phase and elemental composition of supports and films are studied as well as the gas permeability and conductivity of films. It is concluded that composites of calcium zirconate with nickel can be recommended as the supporting anodes for the proton-conducting CaZr_0.9Y_0.1O_3–δ film electrolyte.
