Behavior of oxygem bubbles during alkaline water electrolysis

Growth rate, departure radius and population of oxygen bubbles at the transparent anode during alkaline water electrolysis have been investigated experimentally. The supersaturation of dissolved oxygen in the electrolyte adjacent to the anode surface has been derived from bubble growth rates. Ambient pressure (2–70 kPa) and molarity of the electrolyte (0.1–6.8 M KOH) are used as parameters
