ABSTRACT:
Apparatus for producing high purity oxygen comprising an oxidizing reactor coupled to at least one compartment of an electrochemical cell. Air is used to oxidize a reduced form of a special compound to form a peroxide which spontaneously decomposes to a mixture of the oxidized form of said compound and hydrogen peroxide. This mixture is positoned in the anode compartment of said cell and oxidized to cause the hydrogen peroxide to give off oxygen which is removed and recovered. The oxidized form of said compound is transferred to the cathode compartment wherein it is reduced and then recycled to the oxidizing reactor. The apparatus also provides a filter press-type cell containing a plurality of side-by-side compartmented electrochemical cells formed by alternating bipolar electrodes separated by porous membranes. Means are provided for coupling an oxidizing reactor to the anode compartments; for transferring material from respective anode compartments to respective cathode compartments; for removing product oxygen; and for recycling material from cathode compartments to the oxidizing reactor.
