Method of assembling a bipolar electrolyzer

Claim 2

In a method of assembling a diaphragm cell having a cathode unit containing a plurality of fingered cathodes, and an anode unit containing a plurality of metal anodes extending outwardly from the anode unit, said method comprising the steps of bringing the cathode unit into contact with a slurry, depositing a diaphragm from the slurry onto the fingered cathodes, removing the cathode unit from the slurry, and assembling the anode unit and the cathode unit whereby to form an electrolytic cell having the anodes thereof interleaved between the cathodes thereof, the improvement comprising: providing a barrier between a pair of cathodes during diaphragm deposition on said cathodes; and assembling the anode and cathode units to form a diaphragm cell.

Claim 3

The method of claim 1 comprising placing an electrolyte permeable template having electrolyte impermeable barriers corresponding to and offset from said cathodes around said cathode unit and thereafter depositing the diaphragm onto the cathodes.

Claim 4

The method of claim 1 comprising partially depositing the diaphragm, and thereafter placing the barrier between adjacent cathode fingers.

Claim 5

The method of claim 1 comprising placing covers over alternate cathode fingers.

Claim 6

The method of claim 1 wherein each said anodes are formed of a pair of metal sheets, and wherein said metal sheets are joined together with an acidified sodium chloride brine leachable joint at the end spaced from the anode unit.

Claim 7

In a method of assembling a diaphragm cell having a cathode unit containing a plurality of fingered cathodes, and an anode unit containing a plurality of metal anodes extending outwardly from the anode unit, each of said anodes being formed of a pair of metal sheets, said method comprising the steps of bringing the cathode unit into contact with a slurry, depositing a diaphragm from the slurry onto the fingered cathodes, removing the cathode unit from the slurry, and assembling the anode unit and the cathode unit whereby to form an electrolytic cell having the anodes thereof interleaved between the cathodes thereof, the improvement comprising: joining the anode sheets together with an acidified sodium chloride brine leachable joint at the end spaced from the anode unit; and assembling the anode and cathode units to form a diaphragm cell.

Claim 8

In a method of assembling a diaphragm cell having a cathode unit containing a plurality of fingered cathodes, and an anode unit containing a plurality of metal anodes extending outwardly from the anode unit, each of said anodes being formed of a pair of metal sheets, said method comprising the steps of bringing the cathode unit into contact with a slurry, depositing a diaphragm from the slurry onto the fingered cathodes, removing the cathode unit from the slurry, and assembling the anode unit and the cathode unit whereby to form an electrolytic cell having the anodes thereof interleaved between the cathodes thereof, the improvement comprising: joining the anode sheets together with an acidified sodium chloride brine leachable joint at the end spaced from the anode unit; and assembling the anode and cathode units to form a diaphragm cell.

Claim 9

The method of claim 6 comprising providing a barrier between a pair of cathodes during diaphragm deposition on said cathodes.

Claim 10

The method of claim 7 comprising placing an electrolyte permeable template having electrolyte impermeable barriers corresponding to and offset from said cathodes and said cathode unit and thereafter depositing the diaphragm onto the cathodes.

Claim 11

The method of claim 7 comprising partially depositing the diaphragm and thereafter placing the barrier between adjacent cathode fingers.

Claim 12

The method of claim 7 comprising placing covers over alternate cathode fingers.

Claim 13

In a method of assembling a diaphragm cell having a cathode unit containing a plurality of fingered cathodes, and an anode unit containing a plurality of metal anodes extending outwardly from the anode unit, each of said anodes being formed of a pair of metal sheets, said method comprising the steps of bringing the cathode unit into contact with a slurry, depositing a diaphragm from the slurry onto the fingered cathodes, removing the cathode unit from slurry, and assembling the anode unit and the cathode unit whereby to form an electrolytic cell having the anodes thereof interleaved between the cathodes thereof, the improvement comprising: providing a barrier between a pair of cathodes during diaphragm deposition on said cathodes; joining the anode sheets together with an acidified sodium chlorine brine leachable joint at the end spaced from the anode unit; and assembling the anode and cathode units to form a diaphragm cell.

Claim 14

In a method of assembling a diaphragm cell having a cathode unit containing a plurality of fingered cathodes, and an anode unit containing a plurality of metal anodes extending outwardly from the anode unit, each of said anodes being formed of a pair of metal sheets, said method comprising the steps of bringing the cathode unit into contact with a slurry, depositing a diaphragm from the slurry onto the fingered cathodes, removing the cathode unit from slurry, and assembling the anode unit and the cathode unit whereby to form an electrolytic cell having the anodes thereof interleaved between the cathodes thereof, the improvement comprising: providing a barrier between a pair of cathodes during diaphragm deposition on said cathodes; joining the anode sheets together with an acidified sodium chlorine brine leachable joint at the end spaced from the anode unit; and assembling the anode and cathode units to form a diaphragm cell.
