Abstract: A stack of electrochemical cells for wastewater treatment is disclosed comprising at least one electrochemical cell having a solid polymer membrane, an anode catalyst layer and a cathode catalyst layer adjacent to each side of the membrane, an open pore mesh placed next to each of the catalyst layers and a compression frame placed next to each open pore mesh. A cover is placed between the compression frames of two neighbouring electrochemical cells in the stack thereby forming an enclosure which spans the distance between the two neighbouring electrochemical cells thereby isolating the cathode catalyst layer or the anode catalyst layer from the solution in the reactor tank in which the stack is immersed.

Abstract: An electrochemical cell for wastewater treatment is disclosed comprising a catalyst coated membrane, an open pore mesh placed next to the catalyst coated membrane, on each side of the membrane, and a compression frame placed next to each of the open pore meshes. The open pore meshes and the compression frames are made of a conductive material. Each compression frame has compression arms spread within the area delimited by the perimeter of the frame to apply a uniform compression force across the anode and cathode active areas through fasteners which protrude through the compression arms, the open pore meshes and the catalyst coated membrane. A stack comprising at least one such electrochemical cell is immersed in a reactor tank containing the wastewater to be treated.
