Electrochemical characteristics of samaria-doped ceria infiltrated strontium-doped LaMnO3 cathodes with varied thickness for yttria-stabilized zirconia electrolytes

▶ SDC infiltrated LSM cathodes based on YSZ electrolytes were evaluated. ▶ The infiltrated cathode performance increased with electrode thickness up to 30 μm. ▶ Three main electrochemical processes were observed using electrochemical impedance spectra. ▶ The results from half and full cells was in agreement with that of symmetrical cells. ▶ The maximum power density of 1.1 W cm−2 was achieved at 800 °C.
