Abstract
Exemplary embodiments include a method or apparatus for improving the electrolysis efficiency of high-pressure electrolysis cells by decreasing the current density at the anode and reducing an overvoltage at the anode while decreasing the amount of hydrogen permeation through the cell membrane from the cathode chamber to the anode chamber as the high-pressure electrolysis cell is operated.
