Dynamic Voltage Behavior of a PEM Electrolyzer Under Continuous on/off Loading Cycles Using an Equivalent Circuit Model
Résumé
Mathematical modeling plays a crucial role in the design and performance evaluation of proton exchange membrane (PEM) electrolyzers. Among the various approaches reported in the literature, equivalent circuit models (ECMs) stand out for their simplicity and suitability for studying voltage behavior and interaction with power electronic interfaces. However, the dynamic voltage response of PEM electrolyzers under continuous on/off loading cycles has not been extensively explored. This paper presents a static–dynamic ECM model that accurately describes the voltage response of a PEM electrolyzer subjected to continuous on/off loading cycles in the supply current, represented by square-wave variations. The model parameters are derived from experimental data and validated through laboratory measurements. Thanks to this model, it is possible to have a better understanding of the PEM electrolyzer voltage behavior when intermittent power sources, such as energy conversion systems, are considered.
