Abstract
One embodiment of the present invention includes a technique of performing a catalytic oxidation reaction at an anode to provide hydrogen ions from molecular hydrogen and a catalytic reduction reaction at a cathode to provide hydroxyl ions from liquid hydrogen peroxide. Passage of the molecular hydrogen to a reaction region is impeded with a proton exchange membrane and passage of the hydrogen peroxide to the reaction region is impeded with an ion-selective arrangement. Electric potential is generated between the anode and the cathode to provide electric power from a reaction of the hydrogen ions and the hydroxyl ions in the reaction region. In one variation, a regeneration technique is also provided.
