Abstract

REDUCED VOLUME ELECTROCHLORINATION CELLS AND METHODS OF MANUFACTURING SAME An electrochemical cell includes a cathode and an anode disposed in a housing. Each of the cathode and anode portions extending radially outward from a region proximate a central axis of the housing. A surface area of an active surface of the anode is greater than a surface area of an internal surface of the housing. A surface area of an active surface of the cathode is greater than a surface area of an internal surface of the housing. [Figure 22A]
