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.
