Description
|
This data set contains detailed measurement and set point data from a 100 kW Proton Exchange Membrane (PEM) electrolyzer test rig developed at IET-4, covering the period 2018–2023 with approximately 200 individual data sets. The system was operated under a wide range of user-defined load profiles, e.g. wind power and photovoltaic (PV). All relevant operational data (~120 measurement values) were continuously recorded, including electrical characteristics (voltage and current), temperature distributions, gas flow rates, and efficiency metrics, as well as auxiliary parameters required for detailed system assessment. The data collection campaign was designed to support systematic investigations on electrochemical performance, thermal behavior, start-up and ramping dynamics, and system efficiency. It further enables research on advanced thermal control strategies [1], transient behavior during start-up phases [2], dynamic system modeling [3], data-driven operational optimization [4], and efficiency evaluation [5]. In addition, the dataset provides a robust foundation for material degradation studies, system design optimization, and the development of advanced control loops and operational strategies. More detailed information on the 100 kW PEM electrolyzer test rig can be found in the referenced publications. Information on the structure and organization of the data and the process flow diagram can be found in the the folder "Documentation". (2025-10-08)

The data set is organized in a structured and consistent way. All data files start with “Data_measured”, while the corresponding set point files begin with “Setpoint-Profile”. Set points can either be defined manually or automatically using a predefined set point sequence stored in a file. For each set point file, there exists a corresponding measurement file — but not necessarily the other way around, since some experiments were operated manually without automated set point control. To get an overview of all available measurements, it is recommended to display the data set in "tree structure" view. This provides a quick overview of available measurement days and a short description of what was measured. If a folder contains only one file, the system was operated manually. If a folder contains two files, the experiment was performed automatically using a set point profile.
