Data Content: Data including changes in membrane electrode assembly (MEA) voltage and anode potential under low temperatures, voltage variation and polarization curve data, SEM images, impedance data, cyclic voltammetry scan data, active surface area degradation data, voltage data before and after voltage reversal, etc.
Collection Protocol: Two types of MEAs were prepared using commercial raw materials and IrO₂ synthesized via Adams' method, then assembled into single cells for electrochemical characteristic tests. Our research group separately tested the battery polarization performance, electrochemical impedance, voltage reversal behavior, cyclic voltammetry degradation behavior, etc. Additionally, MEA samples were sent to the testing center for analysis and testing such as their SEM images.
Collection Location: Testing Center and Fuel Cell Research Laboratory of Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
Equipment: Electron microscope (JEOL JSM-IT300); electrochemical workstation (Interface 5000E, Gamry); single cell test bench.
Collection Period: May 2020 to September 2021
