Patent ID: 7754064

Claim:
An apparatus for producing hydrogen peroxide comprising: at least one anolyte chamber, coupled to at least one anode, wherein the anolyte chamber comprises an inlet for liquid anolyte, the anolyte comprising one or more electrolytes; at least one catholyte chamber coupled to at least one cathode, the at least one cathode comprising a carbon fiber cloth cathode anchored by one or more contacts, wherein the catholyte chamber comprises an outlet for product comprising hydrogen peroxide and an inlet for catholyte comprising oxygen-containing gas and liquid electrolyte; at least one anode cation exchange membrane and at least one cathode cation exchange membrane, wherein the anode cation exchange membrane is adjacent to the at least one anode, wherein the cathode cation exchange membrane is in contact with the at least one cathode; and at least one central chamber, wherein the at least one central chamber is disposed between the at least one anolyte chamber and the at least one catholyte chamber, the at least one anode is disposed between the at least one anolyte chamber and the at least one central chamber, the at least one cathode is disposed between the at least one catholyte chamber and the at least one central chamber, and wherein the central chamber comprises an inlet for a liquid electrolytic medium, such that the apparatus is arranged in the following order: the at least one anolyte chamber, the at least one anode, the at least one anode cation exchange membrane, the at least one central chamber, the at least one cathode cation exchange membrane, the at least one cathode, and the at least one catholyte chamber.
