This work aims to investigate, through computational modeling and experimental validation, the electrochemical hydrogen production capacities of various saline solutions (NaCl, KCl, and CaCl2) in a membrane cell system. A combined methodological approach comprising the layered dissection multithreaded algorithm, the PARDISO direct solver, and the Discrete Ordinates Method was used to do the numerical analysis. The electrodialysis process was modeled using COMSOL Multiphysics, which considered electrode surface reactions, ion transport, potential distribution, and charge conservation. An ion exchange membrane of 0.15 mm separated the 1 × 3 mm anode and cathode chambers. 500 mol/m3 of brine was present at the anode inlet. The amounts of OH− and H2 (0–100 mol/m3) differed spatially between electrodes. In order to verify the model, identical experimental settings were used, and there was great agreement between the theoretical and measurable data. In terms of producing hydrogen, KCl fared better than the other electrolytes, but CaCl2 did not perform as well. The results show the great reliability of the suggested numerical model and the important impact of brine composition on the efficiency of hydrogen generation, offering valuable information for improving membrane-based electrochemical hydrogen production systems.
