The phase composition, thermal coefficient of linear expansion and electrical conductivity of Pr1.85Sr0.15Ni1-хCuхO4 (0.0; 0.1; 0.5; 0.9 and 1) Pr2NiO4 and Pr2CuO4 are investigated at air in the temperature range 100–1000°C. The thermal coefficient of linear expansion are in range of (11.2–16.6)⋅10-6 deg-1. The TCLE of some composition close to TCLE of solid electrolyte La0.9Sr0.1Ga0.8Mg0.2O2.85 (LSGM) и Ce0.9Gd0.1O2-δ (CGO). Pr1.85Sr0.15Ni0.1Cu0.9О4 has the highest conductivity at temperatures above 350°С.
