Modeling and optimization of high temperature proton exchange membrane electrolyzer cells

Although high-temperature proton exchange membrane electrolyzer cells (HT-PEMECs) have been promising devices to store energy in recent years, the effect of certain parameters on their performance is still unclear. Therefore, a 2D multiphysics model adopted study related processes electrochemical reactions an HT-PEMEC. The validated by comparison with experimental data. Subsequently, effects applied voltage, anode water mass fraction, gas velocity, and cathode velocity are studied, trends efficiency conversion rate analyzed. Thermoneutral voltage observed through parametric study. Moreover, maximum (54.5%) obtained optimizing operating conditions. This can be regarded as foundation for subsequent control multi-objective optimization research.
