Abstract: Provided are methods for producing expanded metal structures with solid margin separated by aperture regions, and applications thereof. The solid and aperture regions are formed by controlling the actuation of the punch sequence, including by the use of actuated and non-actuated regions along the metal sheet. By way of non-limiting examples, the solid margins facilitate uniform connections to form electrodes, e.g., for use in an electrolytic cell for a water purification system, or electrochemical processes in general, and they facilitate indexing of the expanded metal for downstream processing.

Abstract: An apparatus for generating electrolytic products, including chlorine and ozone, that includes an electrolytic cell having a cathode in a cathode chamber, an anode in an anode chamber, an electrode chamber separating element disposed between the cathode and anode and sight tubes for visualizing the amount of catholyte and anolyte in the electrolytic chambers is provided. The cathode and the anode include first sides, that are contained within the electrode chambers and participate in the cell's oxidation-reduction reactions, and second sides that project outside of the electrode chambers and which may serve as replacement surfaces for the first sides.
