Abstract

PURPOSE:To check corrosion on the metal section of an electrolyzer by feeding a slight current to the bipolar filter press type electrolyzer in such a manner that the voltage of the unit electrolytic cell exceeds 1.4V at the center of the cell but to suc such an extent as not to cause electrolytic reaction when its operation is halted.
