Abstract:
1. A method for making a diaphragm electrode array suitable for use in an electrolysis apparatus using a plurality of individual wire strands for an anode and a plurality of individual wire strands for a cathode that each have two opposing ends and using a diaphragm, the diaphragm having opposing and substantially planar surfaces that each have a surrounding perimeter and is made of a material that passes ions but impedes the passage of gas through the opposing surfaces of the diaphragm, the method comprising: placing the plurality of individual wire strands that comprise the anode while unattached to one another against one surface of the diaphragm such that the opposing ends of each of the individual wire strands are at or beyond the perimeter of the one surface of the diaphragm; placing the plurality of individual wire strands that comprise the cathode while unattached to one another against the other surface of the diaphragm such that the opposing ends of each of the individual wire strands are at or beyond the opposing perimeter of the other surface of the diaphragm; and after placing the individual wire strands against one of the surfaces of the diaphragm, and before any of the individual wire strands are affixed to the diaphragm, pressing each individual wire strand against the perimeter of the diaphragm surface against which the individual wires strands have been placed in a manner that makes a diaphragm electrode array suitable for use in the electrolyzer apparatus.
