چکیده انگلیسی
Proton-conducting reversible solid oxide cells (PC-RSOCs) have attracted much attention for their advantages of working as energy storage devices. In this study, orthorhombic-perovskite structure BaCe0.8âxZr0.2InxO3âδ (xâ¯=â¯0, 0.1, 0.2, 0.3, 0.4) materials have been synthesized. The effect of different indium doping contents on the stability and electrical properties has been investigated. Experimental results reveal that the BaCe0.5Zr0.2In0.3O3âδ possesses the highest proton conductivity with desirable density. Besides, the stability of BaCe0.5Zr0.2In0.3O3âδ is obviously improved in moist air (20â¯vol% H2O) atmosphere. Anode-supported PC-RSOC with BaCe0.5Zr0.2In0.3O3âδ membrane as an electrolyte displays a maximum power density of 151â¯mW·cmâ2 at 700â¯Â°C in solid oxide fuel cell (SOFC) mode. Meanwhile, the PC-RSOC with BaCe0.5Zr0.2In0.3O3âδ electrolyte membrane in solid oxide electrolysis cell (SOEC) mode can also manifest high current density of â729â¯mAâ¯cmâ2 at 700â¯Â°C with an applied voltage of 1.5â¯V, and maintains a stable current density of around â124â¯mA·cmâ2 at 700â¯Â°C with an applied voltage of 1.1â¯V for more than 60â¯h. These encouraging results suggest the potential application of BaCe0.5Zr0.2In0.3O3âδ as electrolyte material for intermediate-temperature PC-RSOCs.
