Three-Dimensional CFD Simulation of a Proton Exchange Membrane Electrolysis Cell

The energy shift towards carbon-free solutions is creating an ever-growing engineering interest in electrolytic cells, i.e., devices to produce hydrogen from water-splitting reactions. Among the available technologies, Proton Exchange Membrane (PEM) electrolysis most promising candidate for coping with intermittency of renewable sources, thanks short transient period granted by solid thin electrolyte. well-known principle PEM electrolysers still unsupported advanced practices, such as use multidimensional simulations able elucidate interacting fluid dynamics, electrochemistry, and heat transport. A methodology simulation therefore needed. In this study, a model presented validated against recent literature case. study analyses impact temperature gas phase distribution on cell performance, providing valuable insights into understanding physical phenomena occurring inside at basis formation rate oxygen. regard two levels (333 K 353 K) complete polarization curve numerically predicted, allowing analysis overpotentials break-up multi-phase flow cell. An in-house developed macro-homogeneous catalyst layers applied electrolysis, independent overpotentials, investigation their dependency cathodic gas–liquid stratification. validates comprehensive multi-dimensional relevantly proposing urgency optimization devices.
