Abstract
The invention provides an electric cell having an anode compartment, a cathode compartment, and a membrane separating said compartments. The cell also has a peroxidation vessel in which sodium anthraquinone-2,7-disulfonate is peroxidized. The peroxide then decomposes to form a mixture of hydrogen peroxide and the anthraquinone oxide. This mixture is fed to the cathode compartment. When the electric cell is operated as a fuel cell, the anthraquinone oxide from the cathode compartment is conveyed to a reduction vessel in which it is reduced by contact with fuel. All or a portion of the reduced anthraquinone is then contacted with oxygen to form the anthraquinone oxide. The electric cell may also be utilized as a storage battery. The invention also includes the method of operating these electric cells.
