摘要:
An electrolysis device, for producing alkaline water from water, includes an electrolysis vessel, a pair of high porous electrodes arranged in the electrolysis vessel, and a cell unit arranged between the positive and negative electrodes. The pair of high porous electrodes respectively serve as a positive electrode and a negative electrode. The cell unit includes a bipolar membrane element and at least one cation exchangeable membrane. The bipolar membrane element has a cation exchangeable side and an anion exchangeable side. The cation exchangeable side is closer to the negative electrode than the anion exchangeable side. The cation exchangeable membrane is arranged between the anion exchangeable side of the bipolar membrane element and the positive electrode, so as to define an alkalic chamber between the bipolar membrane element and the cation exchangeable membrane.

An electrolysis device is disclosed for producing alkaline water from water including an electrolysis vessel, a positive electrode, a negative electrode, a bipolar membrane element, and at least one cation exchangeable membrane within the electrolysis vessel. The bipolar membrane element has a cation exchangeable side and an anion exchangeable side, the cation exchangeable side being closer to the negative electrode than the anion exchangeable side. The at least one cation exchangeable membrane is arranged between the anion exchangeable side of the bipolar membrane element and the positive electrode, so as to define an alkali chamber between the bipolar membrane element and the cation exchangeable membrane. An ionic exchange resin is associated with the vessel, whereby flow of the water though the vessel and the ionic exchange resin produces alkaline water in the alkali chamber. Various options and modifications are possible. A related washing machine such as a dishwasher is also disclosed.

An apparatus including a housing having walls is provided. The walls of the housing each have inner surfaces and outer surfaces. The walls may include apertures extending from the inner surface to the outer surface. The inner surfaces of the walls define a volume. The volume includes an electrode. The volume further includes a water-controlling separator disposed between the inner surface of the housing and the electrode. The water-controlling separator can block a flow of liquid from the electrode through the apertures to the ambient environment while allowing oxidant to flow from the ambient environment through the apertures to the electrode.

摘要:
An electrochemical device comprises an electrochemical cell. The electrochemical cell comprises a composite cation-exchange member including a conductive base and a cation-exchange material in physical contact with the conductive base, a composite anion-exchange member including a conductive base and an anion-exchange material in physical contact with the conductive base; and a compartment between the composite cation-exchange and anion-exchange members. The compartment comprises an inlet for introducing a feed stream, and an outlet for exiting of an output stream out of the compartment. The electrochemical device comprises a control device configured to transmit an electrical current to the composite cation-exchange and anion-exchange members at a regeneration stage in a manner that the conductive base on the composite cation-exchange member loses electrons and the conductive base on the composite anion-exchange member gains electrons.
