Authors pointed out that the optimum conditions existed by the influence of the bubble of between electrodes, and did the modeling for the hydrogen production by the alkaline water electrolysis of natural convection. This research aims to obtain the optimum conditions when the alkaline water was pumped to flow between electrodes. As a result, it has been found that the optimum condition with forced convection qualitatively agrees with that of natural convection by replacing the bubble rising velocity in the model equation with the average velocity of electrolyte of forced convection, yet quantitative matching has not been achieved.
