Ruddlesden-Popper-structured La₂NiO_4+δ oxide has been applied for the first time as the cathode for La_0.9Sr_0.1ScO_3−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.

La 2 NiO 4 +δ阴极与La 0.9 Sr 0.1 ScO3-δ质子传导性氧化物接触的电极性能

首次使用Ruddlesden-Popper结构的La ₂ NiO _{4 +δ}氧化物作为La _0.9 Sr _0.1 ScO3 _-δ质子传导性氧化物的阴极。已经研究了电极和电解质材料的化学相容性。电极性能已通过阻抗光谱法在600–800°C的干燥和潮湿空气条件下进行了研究。考虑到电解质中电子空穴电导率的分流效应，计算了实际的极化电阻值。
