Unraveling the Impact of Reverse Currents on Electrode Stability in Anion Exchange Membrane Water Electrolysis

The data sets below contain raw data for electrochemical and XPS measurements (AEM water electrolysis) performed for three different systems with NiFe-LDH as anode and various cathode catalysts. The research focused on identifying the stability of electro catalysts when subjected to reverse currents in alkaline conditions. Pt-wire pseudo reference electrodes embedded in the flow cells were used to decouple individual electrode potentials. The study mainly used techniques like Polarisation curves and Impedance Spectroscopy to evaluate system performance.下述数据集包含针对阴离子交换膜水电解（AEM water electrolysis）开展的三类体系的电化学测试与X射线光电子能谱（X-ray Photoelectron Spectroscopy, XPS）原始测试数据，这些体系以镍铁层状双氢氧化物（NiFe-LDH）作为阳极，并搭载多种阴极催化剂。本研究旨在探究电催化剂在碱性环境下承受反向电流时的稳定性。研究使用嵌入流动电解池内的铂丝伪参比电极，以实现各电极电位的解耦。本研究主要采用极化曲线（Polarisation curves）与阻抗谱（Impedance Spectroscopy）等技术，对体系性能开展评估。
