Water electrolysis for hydrogen production is of great importance the reliable use renewable energy sources to have a clean environment. Electrolyzers play key role in achieving carbon-neutral target 2050. Among different types water electrolyzers, proton exchange membrane electrolyzers (PEMWEs) represent well-developed technology that can be easily integrated into smart grid efficient management. In this study, discrete dynamic mathematical model PEMWE was developed MATLAB/Simulink simulate cell performance under various operating conditions such as temperature, inlet flow rate, and current density loads. A lab-scale test bench designed set up, 5 cm2 tested at temperatures (40–80 °C) rates (3–12 mL/min), obtaining Linear Sweep Voltammetry (LSV), Cyclic (CV), Chrono-potentiometry (CP), Electrochemical Impedance Spectroscopy (EIS) results comparison adjustment model. Sensitivity analysis variables confirmed temperature are most influential factors affecting voltage. The parametric sensitivity chemical–physical electrochemical parameters also investigated. significant ones were estimated via non-linear least squares optimization fine-tune Additionally, strong correlations between these identified through regression analysis, enabling accurate prediction across studied range.
