Perovskites are materials of very versatile properties. They may be used in various ways and structures. In this work the results of investigation of the Zr_{0.84}Y_{0.16}O_x electrolyte on La_{0.6}Sr_{0.4}FeO_3 perovskite support are presented. The perovskite support was fabricated by iso-axially die-pressing of La_{0.6}Sr_{0.4}FeO_3 powders and sintering at 1150°C. The Zr_{0.84}Y_{0.16}O_x layer was deposited on La_{0.6}Sr_{0.4}FeO_3 by a combination of colloidal suspension and polymer precursor methods. In this way the dense electrolyte layer was prepared at as low temperature as 400°C. This method may be also useful for high-T_c superconductor layers deposition. The chemical interaction between the electrolyte layer and perovskite support was investigated by X-ray diffraction. It was shown that no reaction occurs between cathode and electrolyte until 900°C. Above 1200°C, parameters of the La_{0.6}Sr_{0.4}FeO_3 unit cell increase. It suggests that the reaction between Zr_{0.84}Y_{0.16}O_x and La_{0.6}Sr_{0.4}FeO_3 is accompanied by substitutional changes in the La_{0.6}Sr_{0.4}FeO_3.
