Patent ID: 8323461

Claim:
An electrochemical apparatus for processing a fluid, the apparatus comprising: (i) an anode comprising electrically conducting diamond and at least one elongate aperture having a central region and first and second end regions; (ii) a proton exchange membrane; and (iii) a cover plate; wherein the cover plate partially covers the anode such that the central portion of the at least one elongate aperture is covered and the first and second end regions of the at least one elongate aperture are uncovered, thereby forming at least one aperture inlet and at least one aperture outlet, and wherein the apparatus is arranged such that when a fluid to be processed is introduced into the apparatus via the at least one aperture inlet there exists at least one three phase interface between the anode, the proton exchange membrane and the fluid to be processed and such that the fluid forming part of the three phase interface undergoes forced flow through the apparatus.
