A Three-Dimensional, Multiphysics Model of An Alkaline Electrolyzer

Abstract

As the most mature technology within the electrolysis field, alkaline electrolyzers are expected to play an important role in the energetic transition. Advantages as their simplicity, modularity and low-cost components make it an interesting technology for the near future. However, the fundamental physics are complex as it includes multicomponent, multiphase flow, porous media, electrochemistry and heat transfer. To have a better understanding of these phenomena, the presented work is devoted to the development of a computational fluid dynamic model to better understand the behavior of all the species that are part of this technology.
