A-site deficient semiconductor electrolyte Sr1−xCoxFeO3−δ for low-temperature (450-550 °C) solid oxide fuel cells
Abstract
<p>Fast ionic conduction at low operating temperatures is a key factor for the high electrochemical performance of solid oxide fuel cells (SOFCs). Here an A-site deficient semiconductor electrolyte Sr<sub>1−x</sub>Co<sub>x</sub>FeO<sub>3−δ</sub> is proposed for low-temperature solid oxide fuel cells (LT-SOFCs). A fuel cell with a structure of Ni/NCAL-Sr<sub>0.7</sub>Co<sub>0.3</sub>FeO<sub>3−δ</sub>-NCAL/Ni reached a promising performance of 771 mW cm<sup>−2</sup> at 550 °C. Moreover, appropriate doping of cobalt at the A-site resulted in enhanced charge carrier transportation yielding an ionic conductivity of >0.1 S cm<sup>−1</sup> at 550 °C. A high OCV of 1.05 V confirmed that neither short-circuiting nor power loss occurred during the operation of the prepared SOFC device. A modified composition of Sr<sub>0.5</sub>Co<sub>0.5</sub>FeO<sub>3−δ</sub> and Sr<sub>0.3</sub>Co<sub>0.7</sub>FeO<sub>3−δ</sub> also reached good fuel cell performance of 542 and 345 mW cm<sup>−2</sup>, respectively. The energy bandgap analysis confirmed optimal cobalt doping into the A-site of the prepared perovskite structure improved the charge transportation effect. Moreover, XPS spectra showed how the Co-doping into the A-site enhanced O-vacancies, which improve the transport of oxide ions. The present work shows that Sr<sub>0.7</sub>Co<sub>0.3</sub>FeO<sub>3−δ</sub> is a promising electrolyte for LT-SOFCs. Its performance can be boosted with Co-doping to tune the energy band structure.</p>
