Abstract
The production of high purity oxygen and hydrogen gases can be accomplished utilizing an electrolysis assembly comprising an anode, a cathode, an ion exchange membrane disposed therebetween, an anode chamber, and a cathode chamber. This ion exchange membrane has been multiply impregnated with catalyst and therefore contains internal catalyst sites where hydrogen gas, which diffuses through the ion exchange membrane from the cathode chamber, and oxygen gas, which diffuses through the ion exchange membrane from the anode chamber, react to form water. Reacting the hydrogen and oxygen gases within the ion exchange membrane prevents these gases from contaminating the oxygen stream in the anode chamber and the hydrogen stream in the cathode chamber, respectively.
