Like reference numerals in the drawings refer to the same or similar functions throughout the various aspects.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

1 is a flowchart illustrating a method of manufacturing an electrode for producing hydrogen water according to an embodiment of the present invention.

The present invention is a method for manufacturing an electrode for producing hydrogen water by alternately processing an E-beam evaporator, which is an electroplating and PVD deposition method. Referring to FIG. 1 , an electrode for producing hydrogen water according to an embodiment of the present invention In the method, first, the first film 200 is formed on the upper side of the Ti substrate 100 (Ti substrate) by using an electroplating method (S110).

In an embodiment, the step of forming the first layer 200 ( S110 ) may include electroplating at least one metal among manganese (Mn), iron (Fe), copper (Cu), and nickel (Ni) to form the first first layer ( S110 ). A film 200 may be formed.

That is, as the deposition substrate of the present invention, a Ti substrate, which is often used for commercial electrodes, is used, and after the cleaning process of the Ti substrate, manganese (Mn), iron (Fe), copper A low-cost non-noble metal such as (Cu) or nickel (Ni) is used to form the first layer 200 having a predetermined thickness.

When the formation of the first film 200 is completed in the above-described step S110, the E-Beam vacuum evaporation method (Electronic-Beam Evaporator, a method of depositing by heating an evaporation source using an Electronic-Beam, the melting point of the material to be made A second film 300 is deposited on the upper side of the first film 200 by using the wide mirror (which is often used in this case) (S120).

In one embodiment, in the step of depositing the second layer 300 ( S120 ), the second layer 300 , which is a thin film in nm units, may be deposited using palladium (Pd), which is a platinum-based catalyst material.

The step of forming the first layer 200 ( S110 ) and the step of depositing the second layer 300 ( S120 ) are alternately repeated to form the multilayer electrode 400 having a multilayer structure on the upper side of the Ti substrate 100 . ) is prepared (S130).

In the above-described step S130, the above-described steps S110 and S120 are alternately repeated several times to stack the low-cost metal film and the catalyst material thin film in a multi-layered structure to increase the efficiency through the formation of the metal interface structure.

When the material is deposited to the same thickness, an interface between metals is formed through the multilayer electrode 400 forming a multilayer structure of a thin film with a structure as shown in FIG. 2 , compared to simply depositing the material in two layers On the other hand, higher efficiency can be obtained due to the characteristics between the interfaces.

However, in FIG. 2 , the first act 200 and the second act 300 alternate three times (that is, three first acts 200-1 to 200-3 and three second acts 300-1), respectively. to 300-3), but the cross lamination of the first film 200 and the second film 300 is not limited to three times, and may be performed more according to the needs of the user. Or it may be formed less.

The first film 500, which is a passivation film (a metal oxide film in a state in which normal chemical and reactivity is lost like an anode and oxide film of iron, cobalt, nickel, etc.) on the multilayer electrode 400 manufactured by the above-described step S130) makes (S140).

Here, a methanol-based PVB (Poly Vinyl Butyral, polyvinyl butyral) solution may be used as the passivation film material in the step (S140) of making the first film 500, and the PVB solution in the multilayer structure electrode 400 The first film 500 may be formed by using dip coating or drop-casting & spin-coating.

A second film 600 is made on the multi-layered electrode 400 on which the first film 500 is made so that the first film 500 made in step S140 can act as a passivation film (S150).

Here, in the step (S150) of making the second film 600, the second film 600 can be made using ultrapure water, and the ultrapure water is applied by dip coating or drop-casting & spin-coating. By making the second film, the first film 500 made in step S140, that is, the PVB film, can act as a passivation film that increases the stability of the electrode.

In the method for manufacturing an electrode for producing hydrogen water having the steps as described above, before the step of forming the first film 200 ( S110 ), the Ti substrate 100 for improving the hydrogen decomposition performance of the electrode and improving the precision It may further include a process of cleaning the (not shown in the drawings for convenience of description).

The electrode manufacturing method for producing hydrogen water having the steps as described above uses a relatively thick film and an E-beam evaporator formed of a cheap metal such as Ni using an electroplating method, so that a noble metal or an electric metal catalyst alloy is easily produced Even metals, which are not easily used as decomposition catalysts because they are not made, can have better electrolysis properties by using the interfacial effect.

3 is a graph comparing the stabilization test according to the PVB passivation coating application.

Figure 3 shows the measurement of the current change while constantly applying a voltage of 5V for 12 hours depending on the presence or absence of a passivation film to an electrode made of 1X2cm size.

Before the PVB passivation film is applied, the current decreases over time and the conductivity decreases by about 15%, but it can be confirmed that the conductivity is maintained almost constant when the PVB passivation film according to the present invention is applied.

As described above, the electrode 10 for producing hydrogen water manufactured by the method for producing an electrode for producing hydrogen water according to an embodiment of the present invention is shown in FIG. 2 .

That is, in the electrode 10 for producing hydrogen water, the Ti substrate 100 is positioned on the lowermost side, and a plurality of the first film 200 and the second film 300 are cross-stacked on the upper side of the Ti substrate 100 (Fig. In the case of 2, the multilayer structure electrode 400 (cross-stacked three times) is formed, and the first film 500 and the second film 600 are sequentially formed on the upper side of the multilayer structure electrode 400 .
