  abstract = {<p>Electrochemical conversion of CO<sub>2</sub> to CO is demonstrated with symmetric-structured metal supported solid oxide cells (MS-SOC). Perovskite Pr<sub>0.5</sub>Sr<sub>0.4</sub>Mn<sub>0.2</sub>Fe<sub>0.8</sub>O<sub>3-<italic>δ</italic>
                  </sub> (PSMF) and Pr<sub>6</sub>O<sub>11</sub> catalysts were infiltrated into the MS-SOC cathode and anode, using 3 cycles with firing at 850 {\textdegree}C and 8 cycles with firing at 800 {\textdegree}C, respectively. Upon reduction during operation, the perovskite PSMF was transformed to Ruddlesden{\textendash}Popper structure with a highly efficient electrocatalytic activity. The impact of operating temperature (600{\textendash}800 {\textdegree}C) and overpotential (0{\textendash}1.8 V) on the CO<sub>2</sub> conversion was investigated. The highest CO<sub>2</sub> conversion of 57.2\% was achieved at 750 {\textdegree}C and 1.8 V. During extended operation for 150 h at 750 {\textdegree}C and 1.2 V, a cell demonstrated relatively stable performance, with initial current density of 535 mA cm<sup>-2</sup> and CO<sub>2</sub> conversion of 23\%. Degradation mechanisms were studied by posttest characterization.</p>},
