Abstract

Asymmetric electrochemical cell apparatus, and methods of operating such apparatus to produce electrolyzed water.

First claim

1 - 37 . (anceled)

38 . An asymmetric electrochemical cell comprising:
(a) at least a first electrode layer; (b) at least a second electrode layer; (c) a processor adapted to apply between said first and said second electrodes an electric current suitable to produce hypohalous acid from a solution containing alkali metal cations and halogen anions; and (e) a power supply.

39 . The asymmetric electrochemical cell as claimed in claim 38 , wherein the first electrode layer comprises activated carbon.

40 . The asymmetric electrochemical cell as claimed in claim 38 , wherein the second electrode layer comprises a construct selected from a graphite sheet, a carbon cloth, a carbon paper and a titanium cloth.

41 . An electrochemical towel for producing electrolyzed solutions using an asymmetric electrochemical cell as claimed in claim 38 , comprising:
(a) at least a first electrode layer; (b) at least a second electrode layer; (c) an electrically insulating layer disposed in between said first electrode layer and said second electrode layer; at least one of said first electrode layer, said electrically insulating layer, and said second electrode layer being adapted to absorb a liquid; (d) a processor; and (e) a power supply.

42 . The electrochemical towel as claimed in claim 41 , wherein the processor and the power supply are adapted to apply an electrical current between a first and second electrode layers.

43 . The electrochemical towel as claimed in claim 41 , wherein the first electrode layer comprises activated carbon.

44 . The electrochemical towel as claimed in claim 41 , wherein the second electrode layer comprises a construct selected from a graphite sheet, a carbon cloth, a carbon paper and a titanium cloth.

45 . The electrochemical towel as claimed in claim 41 , which is covered by a cloth suitable to avoid or to reduce mechanical abrasion.

46 . The electrochemical towel as claimed in claim 41 , which is adapted to generate a hypohalous acid from a solution containing alkali metal cations and halogen anions.

47 . A spraying or dispensing device adapted to spray or dispense a liquid containing a hypohalous acid generated using an asymmetric electrochemical cell as claimed in claim 38 .

48 . The spraying or dispensing device as claimed in claim 47 , further comprising:
(a) a vessel containing the electrochemical cell; and (b) a spraying nozzle suitable to spray a liquid contained in said vessel.

49 . The spraying or dispensing device as claimed in claim 48 , wherein the first electrode layer comprises activated carbon.

50 . The spraying or dispensing device as claimed in claim 48 , wherein the second electrode layer comprises a construct selected from a graphite sheet, a carbon cloth, a carbon paper and a titanium cloth.
