Abstract

An electrolytic cell that draws electrolyte from an electrolyte storage container to the inlet of the cell. The inlet of the cell preferably comprises a back flow prevention device that restricts flow of electrolyte from flowing back through the inlet of the cell. Gasses generated by the electrolysis operation, typically primarily hydrogen that is liberated at the cathode surface, forces electrolytic products such as oxidants out of the discharge port of the electrolytic cell, preferably in a continuous flow process.
