Electrical conductivity and thermal expansion materials on the basis of Pr2-ySryNi1-xCuxO4 (x = 0/1: y = 0/0.15) for cathode of medium temperature electrochemical devices
The phase composition, thermal coefficient of linear expansion and electrical conductivity of r1.85Sr0.15Ni1-xCuxO4 (0.0; 0.1; 0.5; 0.9 и 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-? (CGO). Pr1.85Sr0.15Ni0.1Cu0.9O4 has the highest conductivity at temperatures above 350°C.
