摘要：
Ruddlesden-Popper-structured La2NiO4+δ oxide has been applied for the first time as the cathode for La0.9Sr0.1ScO3−δ proton-conducting oxide. The chemical compatibility of the electrode and electrolyte materials has been studied. Electrode performance has been investigated by means of impedance spectroscopy in dry and wet air conditions in the temperature range of 600–800 °C. Real polarization resistance values were calculated taking into account the shunt effect of electronic hole conductivity in the electrolyte.
