Effect of nature of the ceramic component of the composite electrodes based on La<inf>1.7</inf>Ca(Sr)<inf>0.3</inf>NiO<inf>4+δ</inf> on their electrochemical performance

Abstract

The manuscript focuses on the electrochemical performance of the La<inf>1.7</inf>Ca<inf>0.3</inf>NiO<inf>4+δ</inf> (LCNO) and La<inf>1.7</inf>Sr<inf>0.3</inf>NiO<inf>4+δ</inf> (LSNO) based composite cathodes with Ce<inf>0.8</inf>Sm<inf>0.2</inf>O<inf>1.9</inf> (SDC) or BaCe<inf>0.89</inf>Gd<inf>0.1</inf>Cu<inf>0.01</inf>O<inf>3</inf> (BCGCu) ceramic components in contact with BCGCu or BaCe<inf>0.5</inf>Zr<inf>0.3</inf>Y<inf>0.2</inf>O<inf>3</inf>+1wt.%CuO (BCZYCu) proton conducting electrolytes in comparison with La<inf>0.6</inf>Sr<inf>0.4</inf>Fe<inf>0.8</inf>Co<inf>0.2</inf>O<inf>3</inf> (LSFC) and La<inf>0.75</inf>Sr<inf>0.2</inf>MnO<inf>3</inf> (LSM) composite cathodes. © The Electrochemical Society.
