The cell comprises nonconductive dividers, sandwiching neutral electrodes and designed for rapid flow of electrolyte through the cell to limit voltage loss. A positive electrode plate is disposed in the interstitial space of a nonconductive housing, adjacent to the neutral electrodes. At least one terminal connects to the positive electrode. A negative electrode seals the cell and is sealed with an o-ring. The cell may be mounted to a vehicle or other system using a mounting tab, which optionally also functions as a ground. The cell may use gravitic circulation or a circulating pump to cycle electrolyte. The electrolysis cell may be formed of different dimensions, based on the output needs and application, and may be wired in parallel or in series to suit system needs. ## Claims ### Claim 1 An electrolysis cell, comprising a housing formed of nonconductive material, wherein the housing comprises a first and second transverse walls, having an opening edge, a base edge, and two longitudinal edges;
