High performance of anode supported BaZr0.1Ce0.7Y0.2O3−δ(BZCY) electrolyte cell for IT-SOFC

BaZr0.1Ce0.7Y0.2O3−δ (BZCY) electrolyte has been extensively studied as novel electrolyte for intermediate temperature solid oxide fuel cells (IT-SOFCs). In this short communication, we report our progress on the fabrication and characterization of the high performance anode supported BZCY cell. Maximum power density of 650 mW/cm2 at 700 °C is obtained for the single cell with configuration of Ni-BZCY/BZCY (20 um)/SSC-BZCY. Further, significant performance enhancement is observed during long-term stability test at 600 °C under constant voltage of 0.5 V, indicating excellent stability of BZCY under fuel cell operating condition. Those results indicate that BZCY based cell is very promising for practical applications.

► Anode supported thin BZCY electrolyte cell was successfully fabricated.
► High power density of 350 mW/cm2 has been demonstrated at 600 °C.
► Stable operation of 150 h is demonstrated for the BZCY cell at 600 °C.
