Electric cell having peroxidized intermediate forms

An electric cell for producing electric current comprising

• a cathode compartment containing a cathode,
• an anode compartment containing an anode,
• a membrane separating said compartments,
• a peroxidation vessel containing an oxygen feed inlet and adapted to react oxygen with sodium anthraquinone-2-7-disulfonate to form the anthraquinone peroxide of said sodium anthraquinone disulfonate,
• means for containing anthraquinone peroxide formed in said peroxidation vessel while it decomposes into a mixture of hydrogen peroxide and the anthraquinone oxide,
• means for feeding said mixture of hydrogen peroxide and anthraquinone oxide to said cathode compartment wherein hydrogen peroxide is reduced,
• conduit means coupling an outlet of said cathode compartment to a reduction vessel which contains a fuel inlet and adapted to reduce said anthraquinone oxide to the reduced form by reaction with said fuel,
• conduit means coupling an anode outlet with said reduction vessel, and
• means for conveying a portion of the reduced anthraquinone oxide from said reduction vessel to said anode compartment and the remainder of said reduced anthraquinone oxide to said peroxidation vessel.
