An electrochemical cell according to the present disclosure includes a casing provided with an inflow port and an outflow port, a bipolar membrane laminated body in which two or more bipolar membranes are laminated so as to be opposed, electrodes disposed so as to sandwich the bipolar membrane laminated body, and a first diffusion member disposed between the inflow port and the bipolar membrane laminated body, and provided with through holes communicating between the inflow port and the bipolar membrane laminated body. The first diffusion member is formed such that each of the through holes provided in a peripheral edge portion has a larger opening area than an opening area of the through holes provided in a central portion. This can uniformize a flow of water, so that water treatment can be efficiently executed.

Electrochemical cell, water treatment device provided with same, and operating method for water treatment device

An ion exchange membrane is provided with a first cation exchange composition which has a cation exchange group and is formed in a sheet form; a first anion exchange composition which is disposed to be in contact with the first cation exchange composition, has an anion exchange group, and is formed in a sheet form. Furthermore, the ion exchange membrane is provided with a second cation exchange composition which has a cation exchange group, which is formed in a sheet form, and which is disposed to be opposed to the first cation exchange composition, and through which water permeates more easily than in the first cation exchange composition; and a second anion exchange composition which has an anion exchange group, which is formed in a sheet form, and which is disposed to be opposed to the first anion exchange composition, and through which water permeates more easily than in the first anion exchange composition.

Ion exchange membrane, ion exchange membrane laminated body provided with ion exchange membrane, electrochemical cell provided with ion exchange membrane laminated body, and water treatment apparatus provided with electrochemical cell

An ion exchanger includes a sheet-shaped positive ion exchangerin which binder particlesand positive ionic exchange resin particlesare mixed with each other, and a sheet-shaped porous negative ion exchangerin which binder particlesand negative ionic exchange resin particlesare mixed with each other, the positive ion exchangerand the negative ion exchangerare bonded to each other to form an interface, and capacity of the negative ion exchangeris greater than that of the positive ion exchanger. Therefore, the porous ion exchangeris formed and absorbing ability of ion is increased, capacity of the negative ion exchangeris made greater than that of the positive ion exchanger, regenerating ability of the ion exchanger with respect to absorbing ability of ion can be secured, and ion absorption and regeneration processing is carried out efficiently.

Ion exchanger, water treatment device provided with same, and hot water supply device

A polymer heating element includes an electrically insulating base substrate, at least a pair of electrodes made of a plurality of thin metal wires formed on the electrically insulating base substrate, a polymer resistor which is not in direct contact with the pair of electrodes and which has PTC characteristics, and conductive layers which are in contact with both the electrodes and the polymer resistor. The conductive layers include at least a resin component, a conductor component and an additive component.
