Numerical Simulation of the Polymer Electrolyte Membrane Electrolyzer

In the development of renewable energy, polymer electrolyte membrane(PEM) electrolyzer has shown an impressive impact on the production of pure hydrogen gas, that can be used as fuel and energy storage, and oxygen gas.In this study, the numerical simulation was conducted in order to investigate I-V characteristic of PEM electrolyzer.Moreover, the electromechanical performance that is characterized by the polarization curve depends on many parameters.Therefore, the impact of the membrane and electrodes thicknesses and electrodes porosities are presented.
