Validation of mathematical models of Alkaline and Proton Exchange Membrane (PEM) electrolyzers with literature experimental data

This article presents a validation of mathematical models against literature experimental data for alkaline and Proton Exchange Membrane (PEM) electrolyzers. The validation concerns also an Aspen HYSYS alkaline model expected for future large-scale application. The validation demonstrated that simulated outputs closely aligned with theoretical values under various operating conditions, confirming the reliability of these models in predicting electrolyzer performance. This successful validation supports their application in the design and optimization of green hydrogen production systems.
