Intriguing electrochemistry in low-temperature single layer ceramic fuel cells based on CuFe2O4
Abstract
<p>A composite of CuFe<sub>2</sub>O<sub>4</sub> and Gd-Sm co-doped CeO<sub>2</sub> is studied for a single layer ceramic fuel cell application. In order to optimize the cell performance, the effects of sintering temperatures (600 °C, 700 °C, 800 °C, 900 °C and 1000 °C) were investigated for the fabrication of the cells. It was found that the cells sintered at 700 °C outperformed other cells with a maximum peak power density of 344 mW/cm<sup>2</sup> at 550 °C. The electrochemical impedance spectroscopy analysis on the best cell revealed significant ohmic losses (0.399 Ω cm<sup>2</sup>) and polarization losses (0.174 Ω cm<sup>2</sup>) in the cell. The HR-TEM and SEM gave microstructural information of the cell. The HT-XRD spectra showed the crystal structures in different sintering temperatures. The cell performance was stable and the composite material did not degrade during an 8 h stability test under open-circuit condition. This study opens up new avenues for the exploration of this nanocomposite material for the low temperature single component ceramic fuel cell research.</p>
