| Popis: | The actual work focuses on the development of electrochemically active and stable electrodes for a high temperature proton-conducting electrolyte with a perspective of application in intermediate temperature electrochemical devices. The comparative study of the electrochemical performance of the La1.7M0.3NiO4+δ – based (M = Ca, Sr,Ba) composite cathodes with proton-conducting BaCe0.89Gd0.1Cu0.01O3 or oxygen-ionconducting Ce0.8Sm0.2O1.9 ceramic components in contact with the proton-conducting electrolyte BaCe0.89Gd0.1Cu0.01O3 was performed by an impedance spectroscopy in wet air during 1500 h. The composites were used as functional layers in bi-layered electrodes with current collector layers made of 98 wt.% LаNi0.6Fe0.4O3 + 2 wt.%CuO or 99.4 wt.% La0.6Sr0.4MnO3 + 0.6 wt.% CuO. |
