Microstructure-property relations of SOFC electrodes: Importance of microstructural optimization of La(Sr)MnO₃ cathodes on ZrO₂(Y₂O₃) electrolytes

Research output: Contribution to journal › Article › peer-review

Abstract

Microstructure, cathodic polarization, and ohmic losses of cathodes for SOFCs operating around 800 °C are studied. The importance of the electrode microstructure on electrochemical properties is demonstrated using the La_0.85Sr_0.15MnO₃ cathode material on the ZrO₂-8mol%Y₂O₃ electrolytes. It is revealed that the reduction of the current constriction is the key for optimizing electrochemical performance on microscopic level near the three phase boundaries as well as on macroscopic level around contacts with current collectors.
