Chemical compatibility and cation interdiffusion between the double perovskite cobaltites RBaCo2O6−δ (R = Gd, Pr) and proton-conducting electrolyte BaZr0.8Y0.2O3−δ were studied. Chemical interaction was found to occur already at 1100 °C as a r

Oxygen nonstoichiometry and thermodynamic stability of Zn–doped YBaCo4 − xZnxO7 + δ oxides were investigated by solid state coulometric titration and EMF-method, respectively. As a result, significant zinc doping was shown to increase the stabil
