Abstract:
1. An oxygen production system, comprising: at least one electrolysis cell in which one half of the electrolysis cell is operating in an electrolysis mode to generate oxygen and the other half of the electrolysis cell is operating in a fuel cell mode to consume hydrogen to produce water or steam and generate power to reduce energy consumption for the water electrolysis reaction, each electrolysis cell including a proton exchange membrane (PEM) between a cathode electrode and an anode electrode and interconnected to an electrical power source; and an air supply device configured to direct air to the cathode electrode of the electrolysis cell, so that the air is distributed substantially evenly over the surface of the cathode electrode so as to suppress hydrogen gas production and substantially consume the hydrogen in a reaction with oxygen in the air supply to form water or steam at the cathode electrode.
