Abstract:

This patent application discloses an improved semi-fuel cell and an improved cathode used therein. The semi-fuel cell stack comprises a housing, an anode within the housing, a porous cathode within the housing, an aqueous catholyte within the housing, an aqueous anolyte stream flowing in the housing, and a membrane for preventing migration of the catholyte through the porous cathode and into the anolyte stream. In a preferred embodiment of the present invention, the catholyte comprises an aqueous hydrogen peroxide solution, the anolyte comprises a NaOHseawater solution, and the membrane permits passage of OH ions while inhibiting the passage of hydrogen peroxide. The membrane is attached to a surface of the cathode or, alternatively, impregnated into the cathode. 3 figures
