Abstract
The present invention relates to an electrochemical cell having split fluid and current feed. Specifically, the cathode or anode inlet and outlet fluid may be fed from both, rather than from just one end of the electrolyzer. Alternatively, or additionally, the current may be fed to the anode or cathode side of the cell at one point, but may be removed from the opposite end of cell at two points. By feeding the fluid from both ends of the electrolyzer, the internal shunt current within each manifold is reduced, while the active area in the electrolyzer is increased without increasing the overall area of the current distributors. By removing the current from the electrolyzer at two points rather than just one, the voltage required by the electrolyzer may be reduced by half than if the current were removed at just one point.
