摘要: Abstract This work highlights the possibility of application YBaCo4O7+δ-modified materials as cathodes for solid oxide fuel cells based on protonic electrolytes. To reach this goal, basic YBaCo4O7+δ material and its YBaCo3.5Zn0.5O7+δ (YBCZ) YBaCo3.5Fe0.5O7+δ (YBCF) substituted members were successfully synthesized their structural, thermal electrochemical properties evaluated suitability application. It was found that substitution cobalt with zinc results in structural stabilization such “114” phases convergence expansion coefficient selected BaCe0.5Zr0.3Dy0.2O3–δ (BCZD) electrolyte well superior activity below 700 °C. The Ni-BCZD|BCZD|YBCZ cell yields relatively high power density (200 mW cm–2 at 600 °C) exhibits low polarization resistance (0.51 Ω cm2 600 °C). This, combined activation energy values electrode conductivity both symmetrical allow assuming Zn-substituted could be used devices proton-conducting
