During two-phase electrolysis for hydrogen production, bubbles formed at electrodes disrupt electrical properties and electrochemical processes, affecting current density and causing anode effects. This study investigates a model experimental setup featuring a small vertical pin electrode surrounded by a larger counter electrode for alkaline-water electrolysis. The research focuses on measuring the polarization curves, specifically the relationship between intensity and applied voltage under varying conditions such as electro active species concentration and counter electrode diameter. Experimental results demonstrate the impact of these factors on the overall electrical performance of the electrochemical cell. The findings contribute to the understanding of two-phase electrolysis mechanisms and emphasize the importance of optimizing such processes for hydrogen production and other applications. The work highlights the necessity to consider the influence of bubble dynamics on electrochemical behavior, providing insights for improving efficiency in industrial electrolysis systems.
