Electrolyzer apparatus and method of making it
First Claim
1. 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.

Abstract
An apparatus for the electrolytic splitting of water into hydrogen and oxygen gases is disclosed. The apparatus comprises: (i) a first hemi-enclosure; (ii) a second hemi-enclosure; (iii) a diaphragm electrode array positioned between the first hemi-enclosure and the second hemi-enclosure comprising: (a) a diaphragm, that passes ions and impedes the passage of gases, comprising a first side and a second opposed side; (b) a first plurality of electrodes in a first vicinity of the first side of the diaphragm; and (c) a second plurality of electrodes in a second vicinity of the second opposed side of the diaphragm; (iv) a fastener, for leak-tight fastening of the first hemi-enclosure, the diaphragm electrode array, and the second hemi-enclosure, whereby a leak-tight enclosure is formed; (v) contacts, for electrically powering the first and second pluralities of electrodes, and; (vi) pathways, configured to remove hydrogen and oxygen gases from the enclosure.

4. A method for making a diaphragm electrode array using two continuous lengths of an electrically-conductive wire and a diaphragm, the diaphragm having opposing and substantially planar surfaces, an opposing set of perimeter edges, and made of a material that passes ions and impedes the passage of gas through the opposing surfaces, the method comprising:
-
progressively winding one of the wires in a serpentine pattern that includes substantially-straight wire segments spaced across one surface of the diaphragm, each wire segment abutting one surface of the diaphragm and having opposing ends that each constitute part of a loop that extends beyond a perimeter edge of the diaphragm; progressively winding the other wire in a serpentine pattern that includes substantially-straight wire segments spaced across the other surface of the diaphragm, each wire segment abutting the other surface of the diaphragm and having opposing ends that each constitute part of a loop that extends beyond a perimeter edge of the diaphragm; after the progressive windings, affixing each end of each wire segment to the surface of the diaphragm that it abuts at a perimeter edge of the diaphragm, whereby a diaphragm electrode array for use in an electrolyzer apparatus is made. - View Dependent Claims (5, 6, 7, 8)
