Bipolar electrolyzer

摘要

A bipolar, filter press type cell is disclosed having a liquid permeable diaphragm which is particularly suited for the electrolysis of a brine solution to produce chlorine and caustic or the electrolysis of an aqueous alkali metal hydroxide to produce an aqueous alkaline hydrogen peroxide solution. The cell can include a multiplicity of cell units extending generally in a vertical as well as a horizontal direction. A porous, self-draining electrode assembly includes a current distributor in contact with a side of the electrode opposite the electrolyte active side of the electrode.
