Patent ID: 8888968

Claim:
A method for making a diaphragm electrode array using a continuous length of an electrically-conductive wire and a diaphragm, the diaphragm having opposing and substantially planar surfaces, an opposing set of perimeter edges, and being made of a material that passes ions and impedes the passage of gas through the opposing surfaces, the method comprising in the order recited: progressively winding the wire repeatedly around the diaphragm and its opposing set of perimeter edges so as to create substantially straight wire segments spaced-apart from one another across the opposing surfaces of the diaphragm, each substantially-straight wire segment abutting a surface of the diaphragm and having opposing ends that each cross over a perimeter edge of the diaphragm; after the progressive winding, affixing each end of each wire segment to the surface of the diaphragm that it abuts at a perimeter edge of the diaphragm; and trimming each end of the wire that crosses over a perimeter edge of the diaphragm, whereby a diaphragm electrode array for use in an electrolyzer apparatus is made.
