Abstract | 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 BaCe0.8−xZr0.2InxO3−δ(x = 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 BaCe0.5Zr0.2In0.3O3−δpossesses the highest proton conductivity with desirable density. Besides, the stability of BaCe0.5Zr0.2In0.3O3−δis obviously improved in moist air (20 vol% H2O) atmosphere. Anode-supported PC-RSOC with BaCe0.5Zr0.2In0.3O3−δmembrane as an electrolyte displays a maximum power density of 151 mW·cm−2at 700 °C in solid oxide fuel cell (SOFC) mode. Meanwhile, the PC-RSOC with BaCe0.5Zr0.2In0.3O3−δelectrolyte membrane in solid oxide electrolysis cell (SOEC) mode can also manifest high current density of −729 mA cm−2at 700 °C with an applied voltage of 1.5 V, and maintains a stable current density of around −124 mA·cm−2at 700 °C with an applied voltage of 1.1 V for more than 60 h. These encouraging results suggest the potential application of BaCe0.5Zr0.2In0.3O3−δas electrolyte material for intermediate-temperature PC-RSOCs. © 2017 Hydrogen Energy Publications LLC |
