Method and apparatus for controlling two phase flow in electrolytic cells. The present invention is directed to any electrolytic cell, including but not limited to upflow electrolytic cells that comprise parallel electrodes in a vertical orientation. Fluid control strips are preferably added between the anode and cathode electrodes to control flow of fluid and gas bubbles generated between the electrodes in order to avoid the detrimental effects of gas bubbles on the conductivity of the fluid solution, and thereby increase production and operational efficiency of the electrolytic cell.
