Abstract:
One embodiment of the present invention includes a technique of performing a catalytic oxidation reaction at an anode (31) to provide hydrogen ions from molecular hydrogen and a catalytic reduction reaction at a cathode (41) to provide hydroxyl ions from liquid hydrogen peroxide. Passage the molecular hydrogen to a reaction region (24) is impeded with a proton exchange membrane (33) and passage of the hydrogen peroxide to the reaction region (24) is impeded with an ion-selective arrangement (43). Electric potential is generated between the anode (31) and the cathode (41) to provide electric power from a reaction of the hydrogen ions and the hydroxyl ions in the reaction region (24). In one variation, a regeneration technique is also provided.

Abstract:
The present invention provides an electrochemical flow battery for electric energy storage, the said battery uses anode reactive materials (the material being oxidized during battery discharge) selected from complexed ionic form of late 3d transition metals, i.e., Mn, Fe, and Cu. The battery has significantly low cost due to use of these relative inexpensive metals.
