This work is devoted to the determination of chemical diffusion coefficients (Dchem) and surface oxygen exchange constants (Kchem) for double perovskite of the composition PrBaCo2-xFexO6-δ (x = 0; 0.2), which is a promising cathode material.There are already works devoted to determining the parameters of oxygen transport in PrBaCo2O6-δ, but the influence of the doping degree of the base compound on these parameters has been little studied. Within the framework of this work, for the studied compounds, the values of oxygen nonstoichiometry were determined by thermogravimetric analysis. Dchem and Kchem were determined by the method of relaxation of the total electrical conductivity (ECR).
