Oxygen, chlorine, etc., in addition to hydrogen, may be added to the hydrogen water produced by the seawater electrolysis due to a small amount of salt contained in the electrolytic water or an overvoltage applied to the electrolytic cell to electrolyze the water, There is a problem that exists.

In addition, since hydrogen is a non-polar gas and has a very low solubility in water, it is difficult to generate hydrogen water at a high concentration in the conventional hydrogen generator, and hydrogen gas in a neutral or weak acid region is generated.

In order to solve the above problem, the applicant of the present invention has proposed a separation membrane using a separation membrane such as a solid polyelectrolyte membrane between electrodes and a gas discharge port for discharging oxygen and other substances generated as a by- Thereby providing a hydrogen-containing water generating apparatus.

However, in such a case, ozone, chlorine, and hypochlorous acid ions generated during electrolysis of water may be discharged to the outside, which may adversely affect the environment of the water producing apparatus, and moisture may not be supplied to the separator The separation membrane is dried, which deteriorates the ion conductivity of the separation membrane and deteriorates the water generation performance.

In addition, since hydrogen is a non-polar gas and has a very low solubility in water, it is difficult to generate hydrogen water at a high concentration in the existing hydrogen peroxide and there is a problem that hydrogen in a neutral or weak acid region is generated.

When the upper cap 200 is fastened to the main body 100, But does not limit the manner of fastening. However, according to Henry's law that the amount of gas that can be dissolved in the same amount of liquid at the same temperature is directly proportional to the partial pressure of the gas, the upper cap 200 and the main body 100 are fastened Accordingly, it is needless to say that a high-pressure packing or the like may be further provided in an area where the upper cap contacts the main body. It is needless to say that the above-described fastening by screwing or the like can also be used at the time of fastening between the other components to be described later, and a sealing member (o-ring, Packing, etc.) may be further provided.

FIG. 2 is a detailed view of an electrode module 300 and a composite module 400 in a hydrogen-water producing device according to an embodiment of the present invention. 2, the electrode module 300 may include a first electrode 310 and a second electrode 320 facing each other with the ion exchange membrane 330 interposed therebetween, and the composite module 400 may include a water supply member disposed under the electrode module 300 in contact with the electrode module 300.

The first electrode 310 and the second electrode 320 of the electrode module 300 may be a porous electrode through which a fluid can pass (a fluid can move). The porous electrode may be of a mesh shape having through-hole pores, a plate shape having perforated holes, or the like, but is not limited thereto. In order that the electrode area is maximized and hydrogen generated by the electrolytic reaction can be quickly and easily discharged to the outside of the electrode module, the porous electrode is formed by a plurality of perforated holes, which are porous, square, Shape.

The electrode material of the first electrode and the second electrode may be an electrode material conventionally used for electrolysis of water in the prior art. As a specific example, the first electrode and the second electrode may be platinum electrodes or dimensionally stable electrodes coated with sintered platinum group elements, respectively, but are not limited thereto.

The electrode module 300 may be a laminate of at least the first electrode 310, the ion exchange membrane 330, and the second electrode 320, which is press-coupled in detail, . That is, the two electrodes and the ion exchange membrane may be in close contact with each other at a zero gap. In this case, the electric power consumed in electrolysis can be minimized, which is more advantageous.

Accordingly, the electrode module 300 applies a compressive force to the stacked body of the first electrode 310, the ion exchange membrane 330, and the second electrode 320 in the stacking direction, and the first electrode 310 - (330) and the second electrode (320).

As the water supply member of the composite module 400 is positioned in contact with the electrode module 300 at the lower portion of the electrode module 300, the binding member may include the first electrode 310, the ion exchange membrane 330, The electrode module 300 and the composite module 400 can be brought into close contact with each other.

2, the binding member may include at least a first electrode 310, an ion exchange membrane 330, and a second electrode 320, which are extended from the upper plate and the upper plate, An upper binding member 341 including a side surface surrounding the periphery of the composite module 400 and a lower binding member 342 surrounding the side surface of the composite module 400 and fastened to the lower side of the side surface of the upper binding member. At this time, pressure can be applied to the laminate by the protrusions of the upper plate, and the upper and lower binding members 341 and 342 are fastened together and pressure is applied to the laminate, As shown in Fig. At this time, in order to form a zero gap, the pressure applied to the laminate (the pressure to be applied and maintained) is preferably 0.5 kgf / cm 2 or more, and from 0.5 kgf / cm 2 to 2 kgf / cm 2 in terms of preventing physical damage due to excessive pressure Is applied. At this time, the electrode contacting the moisture supply member of the composite module 400 may be the anode, and the electrode to which the pressure is applied by the protrusion may be the cathode.

The above-described binding member is configured such that the product containing hydrogen generated by the electrolytic reaction in the electrode module 300 is discharged through one side of the composite module 400 (the opposite side on the side in contact with the electrode module) The role of sealing the composite module can also be performed. By this sealing, the discharge of the product containing hydrogen can be made directionally. By this directional discharge, the hydrogen gas can be effectively introduced into the artillery described later, and the amount of dissolved hydrogen can be increased. At this time, in order to prevent the product containing hydrogen from flowing out in the fastening region when the upper end of the hollow fastening member 342 in which the composite module is located is fastened to the lower side of the upper binding member 341 and the inside thereof , And the binding member may include a hooking protrusion formed around the upper end of the lower binding member 342 and may further include a sealing member 343 such as an O-ring inserted into the hole caused by the hooking protrusion.

3 is a cross-sectional view illustrating the composite module 400 in detail in the apparatus for producing hydrogenated water according to an embodiment of the present invention. 3, the composite module 400 may include a moisture supplying member 410 including a hydrophilic polymer having a moisture absorbing ability, and may include a water supplying member 410 The adsorbing member 420 may be disposed below the adsorbing member 420.

The moisture supply member 410 can prevent the ion exchange membrane from drying by supplying water to the ion exchange membrane provided in the electrode module when the apparatus is not used (i.e., when no water exists in the body). The water supply member 410 may include a hydrophilic polymer having a hygroscopic property. Such a hydrophilic polymer absorbs moisture passing through the ion exchange membrane and the electrode during use of the apparatus (i.e., when water is present in the body) And when the apparatus is not used, a small amount of water is continuously released to supply moisture to the ion exchange membrane, thereby preventing the performance of the ion exchange membrane from drying due to drying.

Examples of the hydrophilic polymer having a moisture absorbing ability include cellulose and derivatives thereof (hydroxypropylmethylcellulose (HPMC), hydroxyethylcellulose (HPC) and the like); Polysulfone resins; Hydrophilic acrylic resins (polyacrylonitrile, polyacrylic acid, polyacrylate, etc.); (Polyethyleneglycol (PEG) and the like), polyvinylpyrrolidone, and the like, but it is not limited as long as it is a polymer capable of absorbing moisture during use and continuously supplying water during use.

However, preferably, the hydrophilic polymer having a moisture absorbing ability may be a swelling polymer. That is, the hydrophilic polymer may be a polymer that absorbs water and swells. The swelling polymer is advantageous because it can absorb more moisture even with a small amount of the swelling polymer, and the swelling amount of the swelling polymer increases the area for supplying water, thereby more effectively supplying moisture to the ion exchange membrane. Further, when the water supply member includes a fibrous swelling polymer, the fiber is expanded into pores (for example, perforation holes) of the porous electrode as an open space, so that the movement of the fluid (water and hydrogen gas, etc.) It is possible to directly supply water to the ion exchange membrane.

The swellable polymer is preferably selected from the group consisting of hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose, carboxymethylcellulose, methylcellulose, ethylcellulose, polyethylene, polyvinylpyrrolidone, Polyvinyl alcohol, polyvinyl acetate, polyvinylpyrrolidone-polyvinyl acrylate copolymer, polyvinyl alcohol-polyethylene glycol copolymer, polyvinylpyrrolidone, polyvinylpyrrolidone, polyvinylpyrrolidone, Polyvinyl acetate copolymer, polyvinyl pyrrolidone-polyvinyl acetate copolymer, and a derivative thereof.

In view of securing the flow (fluidity) of the fluid (such as water and hydrogen gas) through the water supply member 410, the water supply member 410 is made of a porous matrix containing fibers of hydrophilic polymer or a porous matrix Matrix. Examples of the porous matrix include, but are not limited to, fabrics made of natural fibers or synthetic fibers (woven or nonwoven fabric) and the like. When the water supply member 410 includes fibers of a hydrophilic polymer, the water supply member may include a woven or nonwoven fabric of hydrophilic polymer fibers and natural fibers (and / or synthetic fibers). The content of the hydrophilic polymer contained in the water supply member 410 is not particularly limited. However, from the viewpoint of stable supply of water at the time of non-use, the water supply member is composed of 5 parts by weight of a porous matrix (or natural fiber or synthetic fiber) To 20 parts by weight of a hydrophilic polymer.

In addition, the moisture supply member 410 may further include a porous inorganic substance coated or embedded in the porous matrix. The porous inorganic material may be particulate and / or fibrous, and the water release rate of the water supply member 410 may be controlled by the porous inorganic material. In detail, the porous inorganic material can play a role of continuously and gradually releasing water absorbed by the hydrophilic polymer. Examples of the porous inorganic material include activated carbon particles, activated carbon fibers, zeolite particles, bentonite particles, and porous alumina, but the present invention is not limited thereto. The porous inorganic material may be embedded in the porous matrix or coated on the porous matrix surface. Needless to say, the porous inorganic material may be bound to the porous matrix by using the above-described hydrophilic polymer as a binder, if necessary. The porous inorganic material content of the water supply member 410 is not particularly limited, but may be 5 to 50 parts by weight based on 100 parts by weight of the porous matrix (or natural fiber or synthetic fiber) in terms of long-term stable supply of water at the time of non-use . The weight average molecular weight of the hydrophilic polymer is not particularly limited, but may be 1,000 to 50,000.

The adsorption member 420 provided under the water supply member 410 adsorbs and removes by-products such as chlorine and ozone generated during the production of hydrogen water. The adsorption member 420 may contain activated carbon, and in a practical example, the adsorption member 420 may be an activated carbon block. During electrolytic reaction of water, gases such as chlorine and ozone, which are generated in the form of gas in the electrode, are released to the outside of the water-producing apparatus, which may cause problems such as odor and corrosion. Such activated carbon blocks can adsorb and remove such chlorine, ozone, and the like, and can be prevented from being released to the outside of the hydrogen-water producing device.

In the embodiment shown in FIG. 3, the composite module 400 includes the water supply member 410 and the adsorption member 420, but the present invention is not limited thereto. In detail, when the porous inorganic material of the water supply member 410 is activated carbon particles and / or activated carbon fiber, chlorine, ozone, etc. can be removed by the water supply member 410, May be separately provided. It is also possible that the porous matrix of the water supply member 410 is a fabric (woven or nonwoven fabric) of activated carbon fibers or the water supply member 410 is a fabric of hydrophilic polymer fibers, activated carbon fibers and natural (or synthetic) Nonwoven fabric), since the water supply member can simultaneously perform the function of the adsorption member, it is not necessary to separately provide the adsorption member.

The shape of the composite module (the water supply member and the adsorption member) may be such that the hydrogen gas emitted from the electrode module is in close contact with the electrode module and can be discharged through the composite module without a leak. For example, the composite module may have a shape corresponding to the electrode of the electrode module, and the cross-section in the direction of stacking with the electrode module may be a circle, a square, a shape of a pentagonal or octagonal plate, but is not limited thereto.

In the apparatus for producing hydrogenated water according to an embodiment of the present invention, the ion exchange membrane of the electrode module may be an anion exchange membrane. At this time, the anion exchange membrane may include a solid polymer electrolyte membrane (anion exchange resin membrane) having selective permeability to anions or a membrane coated with an ion selective solid polymer (anion exchange resin) having an anion exchange group in a porous sintered metal support. When the ion exchange membrane is a cation exchange membrane, the electrolysis reaction of water occurs according to the following reaction formula 1. On the other hand, when the ion exchange membrane is an anion exchange membrane, electrolysis reaction of water may occur according to the following reaction formula 2.

(Scheme 1)

Cathode 2H ⁺ + 2e ^- ? H ₂ (g)

Anode H ₂ O → 1 / 2O ₂ (g) + 2H ⁺ + 2e ^-

(Scheme 2)

Cathode 2H ₂ 0 + 2e ^- ? H ₂ (g) + OH ^-

Anode 2OH ^- ? H ₂ O + 2e ^- + 1 / 2O ₂ (g)

That is, when the ion exchange membrane is a cation exchange membrane, H ⁺ ions are present on the cathode side, thereby generating a slightly acidic hydrogen. However, when an anion-exchange membrane is used, OH-ions are present on the cathode side, and therefore, alkaline water can be produced.

4 is a cross-sectional view illustrating a cross-section of the hydrogen-water producing device according to an embodiment of the present invention. As shown in FIG. 4, the hydrogen generation apparatus according to an embodiment of the present invention includes a hydrogen generator 600 disposed at an upper portion of the electrode module 300, ). ≪ / RTI > The forcogenerator may be a cylindrical shape including a cylinder, and may have a cylindrical shape in which at least one hole through which fluid (hydrogen gas, water, etc.) is discharged is formed on the side of the clogged upper end, and a slit is formed at the lower end.

3, the hydrogen bubbles generated in the electrode module 300 are moved to the composite module 400 through the lower part of the electrode module 300 by the binding member sealing the upper and the side portions of the electrode module, The electrode module 300 may be exposed through the opposite surface of the surface contacting the electrode module 300. As described above, the hydrogen gas selectively discharged to the one surface of the composite module by the binding member flows into the interior of the internal combustion engine, and water equivalent to the gas volume fraction formed by the hydrogen gas introduced into the interior of the internal combustion engine To the space between the cannula and the main body, and then to the bottom of the cannula. Through this process, the amount of hydrogen gas produced by the electrolysis reaction can increase as the contact time with water increases. The ratio of the diameters of the main body 100 and the gas pipe 600 affects the hydrogen gas capture rate, the circulation rate of water, and the mixing characteristics of water and hydrogen gas. The diameter ratio of 0.4 to 0.6 is advantageous for producing a high concentration of hydrogen water having a high dissolved hydrogen content. In this case, the impeller and the main body may each be cylindrical. As shown in FIG. 4, in the electrode module 300 and the composite module 400 that are joined by the fastening member, a space is formed at a side of the gas discharge side that is spaced apart from the complex module by a certain distance, And a gas exhaust member 344 having at least one side through-hole connected thereto. That is, the gas discharging member 344 discharges the gas generated in the electrode module through the side through hole, thereby moving the gas phase more smoothly to the upper portion of the electrode module.

5 is a cross-sectional view illustrating an upper cap 200 in the apparatus for producing hydrogen according to an embodiment of the present invention. The upper cap 200 may include a housing-shaped receiving member 210 having an open top and a first cap 220 and a second cap 230. The housing member 210 has a housing shape and can store dry food or the like. The first cap 220 may be coupled to one side (upper side) of the accommodating member 210 to open the first side of the accommodating member 210 And can be fastened to the first cap 220 and the main body 100. At this time, the housing member 210 may be attached to the second cap surrounding the housing member 210, and the top of the second cap may be clogged by the housing member 210, but the present invention is not limited thereto.

As described above, the housing member 210 may be for storing dry food, and the dry food may include dry plants such as tea, fruit, and vegetables. This makes it possible to conveniently produce a beverage or a favorite food using the high-concentration alkaline hydrogen-containing water produced through the apparatus for producing hydrogenated water.

In the hydrogen generating apparatus according to an embodiment of the present invention, the power supply unit 300 may further include a controller. At this time, the control unit determines whether or not the electric energy is supplied to the electrode module by a signal through the power button or the like, and the magnitude of the voltage applied to the electrode module according to the use conditions such as the water quality of the raw water, It is possible to control the electrolysis conditions such as the application time and the like.

In detail, the control unit receives the electric conductivity of the raw water at the point of time when the raw water is inputted and the electrolysis reaction is not performed to convert it to the use time of the generating apparatus, and controls the electrolysis condition based on the conductivity of the raw water. can do.

According to Faraday's law, the amount of material produced by electrolysis is given by Equation 1 below.

(Equation 1)

는 전도율, V는 인가 전압, t는 시간(sec), d는 전극간의 거리(cm), A는 전극 면적, n은 반응전자수이다.M is the amount of material produced by electrolysis, m is the atomic weight (or molecular weight) of the product, F is the Faraday constant,

V is the applied voltage, t is the time (sec), d is the distance between the electrodes (cm), A is the electrode area, and n is the number of reacting electrons.

As shown in Equation 1, the amount of material produced by electrolysis is proportional to the voltage and proportional to the conductivity of water. However, the conductivity of the raw water is inevitably changed due to the fact that the raw water used for generating hydrogen water differs depending on the user and the place of use, and the conductivity of the raw water may also be changed depending on the environment (temperature) to be used.

Therefore, even when the conductivity of the raw water (water) used for generating hydrogen water changes by controlling the voltage and / or the time applied to the electrode module based on the electric conductivity by receiving the electric conductivity of the raw water, Hydrogen water having constant concentration and pH can be produced.

To this end, the controller applies a voltage to the electrode module before applying the voltage for the electrolysis reaction to the electrode module, and controls the current flowing between the two electrodes of the electrode module at the corresponding voltage detected by the current detector, The electric conductivity of the raw water is calculated, and the electrolysis conditions applied to the electrode module can be controlled based on the calculated electric conductivity. A specific, non-limiting example is the first group having a relatively high electrical conductivity of the raw water, the third group having a relatively low electrical conductivity, and the electrical conductivity between the first and third groups (Voltage and / or electrolysis time) according to the stored electrolysis conditions (voltage and / or electrolysis time) for each group (the first group, the second group, or the third group) Thus, hydrogen water having a constant dissolved hydrogen concentration and pH can be produced regardless of the user, the use area, and the use environment. At this time, the power supply unit 300 may further include a conventional storage unit such as a normal nonvolatile memory together with the control unit. In the storage unit, the electricity of each group including the first group, the second group, Conductivity range and electrolytic conditions (such as voltage and / or electrolytic time) according to each predetermined group can be stored.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Those skilled in the art will recognize that many modifications and variations are possible in light of the above teachings.
