Claim 30:
31. A method of assembling an electrochemical cell for wastewater treatment of claim 1 comprising the steps of:
a. providing a solid polymer electrolyte membrane, an anode catalyst layer adjacent to a first side of the solid polymer electrolyte membrane and a cathode catalyst layer adjacent to a second side of the solid polymer electrolyte membrane, opposite to the first side;
b. positioning a first open pore mesh adjacent to the anode catalyst layer and a second open pore mesh adjacent to the cathode catalyst layer, wherein the first open pore mesh and the second open pore mesh each comprise a flat surface and an embossed surface which is raised from the flat surface;
c. positioning a first compression frame, adjacent to the first open pore mesh and a second compression frame, adjacent to the second open pore mesh, each of the compression frames having compression arms connected to each other at connection sites and being spread within the area delimited by the perimeter of the frame;
d. inserting fasteners through holes provided in the compression arms of the first and second compression frames at the connection sites, through holes provided in the first and second open pore meshes and through the solid polymer electrolyte membrane and the anode and cathode catalyst layers, and
e. compressing the solid polymer membrane, the first open pore mesh, the second open pore mesh between the first compression frame and the second compression frame at the connection sites through a compression force provided by the fasteners,
wherein the connection sites are distributed within the area delimited by the perimeter of the frame to provide a substantially uniform compression force over an area of the electrochemical cell delimited by the compression frames.
