Compositional optimization of ceramic composite electrodes without metal catalysts for steam and CO2 electrolysis

Syngas Production from CO2 and H2O via Solid-Oxide Electrolyzer Cells: Fundamentals, Materials, Degradation, Operating Conditions, and Applications

“…At an applied voltage of 1.3 V, the electrolysis-current densities were 0.32 and 0.46 A cm −2 for the LBM and La 0.5 Ba 0.5 Mn 0.7 Co 0.3 O 3−δ fuel electrodes, respectively. Erdienzy et al 174 used the infiltration method to prepare La 0.8 Sr 0.2 Mn 0.5 Fe 0.5 O 3 composite electrodes and found that the nonohmic resistance of the associated cell (0.36 Ω cm 2 ) was half that of the LSCM cell (0.69 Ω cm 2 ), which indicates that the La 0.8 Sr 0.2 Mn 0.5 Fe 0.5 O 3 cell exhibited superior electrode performance.…”
