Enhancing sinterability and electrochemical properties of Ba(Zr0.1Ce0.7Y0.2)O3-δ proton conducting electrolyte for solid oxide fuel cells by addition of NiO

Proper amount of NiO addition can enhance the sinterability of proton conducting perovskite BZCY7. A SOFC with the optimized 0.5 wt% NiO modified BZCY7 electrolyte, which is well densified at 1400 °C, shows a high electrochemical performance.586
