Primary to ternary current distribution

During two-phase electrolysis for hydrogen or fluorine industrial production, bubbles created at vertical electrodes significantly disturb electrical properties and electrochemical processes. These bubbles serve as motion sources for flow within the electrolysis cell, leading to a strong coupling between hydrodynamic properties, species transport, and electrical performance. Consequently, the presence of bubbles alters both global and local properties, notably modifying the current density distribution within the electrolysis cell. This study aims to present a thorough electrochemical engineering investigation and modeling of the two-phase electrolysis properties in the vicinity of the electrode. The research emphasizes the need for improved understanding of the actual interface conditions during electrolysis, aimed at optimizing processes and preventing electrode consumption. The findings underscore the importance of considering two-phase phenomena, particularly in the context of growing interest in efficient hydrogen production and sustainable fluorine generation, particularly for the nuclear industry.
