Surface Modification of La0.8Sr0.2MnO3 Oxygen Electrode of Solid Oxide Cells by La2NiO4 Infiltration

The effects of introducing La2NiO4 nanocatalyst on the electrochemical performance of La0.8Sr0.2MnO3 is investigated under solid oxide electrolysis cell and fuel cell modes, as well as open circuit voltage. Extracted data from impedance spectroscopy are interpreted with the analysis of distribution of relaxation times.本研究探究了引入La₂NiO₄纳米催化剂（La2NiO4 nanocatalyst）对La₀.₈Sr₀.₂MnO₃电化学性能的影响，实验分别在固体氧化物电解池（Solid Oxide Electrolysis Cell）模式、燃料电池模式以及开路电压（Open Circuit Voltage）条件下开展。研究通过弛豫时间分布（Distribution of Relaxation Times）分析法，对阻抗谱（Impedance Spectroscopy）提取得到的实验数据进行了解释。
