Development of anode-supported electrochemical cell based on proton-conductive Ba(Ce,Zr)O3 electrolyte

This study shows the fabrication process of an anode-supported proton-conductive cell, then the electrochemical performances were investigated under SOFC mode in a wide temperature range from 222 to 486 °C. Ba(Ce0.7Zr0.1Y0.1Yb0.1)O3-δ (BCZYYb) was selected as an electrolyte material, and Ni-BCZYYb cermet and (La,Sr)(Co,Fe)O3-BCZYYb composite were selected as a fuel and an air electrodes materials, respectively. The cell showed open circuit voltages over 1.1 V and worked as a SOFC within the whole temperature range.
