Abstract

The present invention provides a membrane-electrode assembly which includes: at least one rod-form or tubular electrode; a tubular diaphragm disposed around the periphery of the electrode; and a wire-form counter electrode disposed around the periphery of the diaphragm, the diaphragm being fixed to the rod-form or tubular electrode with the wire-form counter electrode to thereby form an electrode chamber having a gas/liquid passage between the diaphragm and the rod-form or tubular electrode.

Claims (16)

1. An electrolytic cell which comprises:

a membrane-electrode assembly, which comprises an electrode chamber having at least one opening;

a feeder wire-fixing tube fitted to the at least one opening of the electrode chamber of the membrane-electrode assembly;

a feeder wire fixed between the at least one opening and the feeder wire-fixing tube,

wherein the membrane-electrode assembly comprising at least one rod-form electrode placed in a diaphragm which is preformed into a tube, thereby forming a tubular diaphragm;

the tubular diaphragm disposed around the periphery of the rod-form electrode; and

a wire-form counter electrode spirally wound around the periphery of the tubular diaphragm,

the tubular diaphragm being fixed to the rod-form electrode with the wire-form counter electrode so that the tubular diaphragm is in contact with at least a part of the rod-form electrode and the tubular diaphragm is in contact with at least a part of the wire-form counter electrode to thereby form the electrode chamber,

the electrode chamber having a spiral shape and having a gas/liquid passage between the tubular diaphragm and the rod-form electrode,

wherein the rod-form electrode is an anode and the counter electrode is cathode,

wherein the rod-form electrode comprises diamond, and

wherein the wire-form counter electrode is spirally wound at a pitch of 1-10 mm.

2. The electrolytic cell of claim 1 , wherein the membrane-electrode assembly comprises a plurality of rod-form electrodes.

3. The electrolytic cell of claim 1 , wherein a tube for forming a tubular counter electrode chamber is disposed around the electrode chamber and the counter electrode.

4. The electrolytic cell of claim 1 , which yields electrolytic water, the electrolytic water comprising ozonized water as a main component.

5. The electrolytic cell of claim 3 , which yields electrolytic water, the electrolytic water comprising ozonized water as a main component.
