Hereinafter, a method and an apparatus for generating electrical energy using seawater according to the present invention will be described in detail with reference to the accompanying drawings.

A method of generating electrical energy using seawater according to the present invention will be described with reference to FIG. 1. First, one anode is made using silver chloride (AgCl) as the reduction material (step 10), and one cathode is made by pressing magnesium (Mg) or aluminum (Al) alloy as the oxidation material (step 20). .

Thereafter, the prepared positive and negative electrodes are installed in one reaction reservoir. At this time, the inner side wall of the reaction reservoir is provided with an outlet and an inlet of the sea water through which the sea water can be distributed to the inside, and a single section of the electric seawater battery is completed by covering a single polymer isolation layer between the anode and the cathode (step 30).

Thereafter, seawater is introduced into the reaction reservoir, and the introduced seawater is used as an electrolyte for the positive and negative electrodes in the reaction reservoir. That is, Mg ⁺² + 2e- is oxidized in the cathode to lose electrons and 2AgCl + 2e-> 2Ag + 2Cl- is reduced in the cathode to obtain electrons. Can be output (step 40).

Referring to Figure 2 the process for producing a positive electrode of the seawater battery as follows.

First, the silver ingot is dissolved in a solution of nitric acid (HNO ₃ ), and sodium chloride (NaCl) powder is added to the resulting silver nitrate (AgNO ₃ ) to produce a silver chloride (AgCl) precipitate, which is boiled (step 101), and then the silver chloride is filtered. The precipitate of (AgCl) is filtered to remove impurities (step 102), and then purified to obtain high purity silver chloride (AgCl) (step 103). Thereafter, the obtained silver chloride (AgCl) is dried to obtain a high purity silver chloride (AgCl) in powder form (step 104), and the silver chloride (AgCl) powder is subjected to high temperature melting (step 105), followed by cooling to perform mold peeling treatment. After that (step 106), the hot rolling process is performed (step 107). Finally, by pressing (step 108) and developing (step 109), a positive electrode having a solid appearance is formed.

The seawater battery made in this way has the configuration as shown in FIG. A cathode output terminal 51 protruding out of the reaction reservoir 7 is formed by installing the cathode 5 at a predetermined position above and below the reaction reservoir 7 and welding one conductive wire thereon, and the anode 6 is formed. Is installed at a predetermined position between the pair of cathodes (5) and by welding one nickel guide plate thereon an anode output terminal (61) protruding out of the reaction reservoir (7) is formed, and the cathode (5) and the anode (6) It is possible to prevent electrical contact occurring between the anode and the cathodes 6 and 5 by covering the single-layer polymer isolation layer 8 between the two layers.

The reason why seawater flows into the reaction storage tank 7 as an electrolyte for chemical reaction is because the seawater contains various kinds of chemical elements. For example, magnesium dichloride (MgCl ₂ ), sodium chloride (NaCl), and the like are chemical elements contained in seawater. Therefore, when the seawater is circulated through the inlet and outlet of the reaction storage tank 7, the magnesium (Mg) or aluminum (Al) alloy is used as an oxidation reaction material to oxidize Mg-> Mg ⁺² + 2e- to the cathode. To cause the loss of electrons and output through the cathode output stage 51, using silver chloride (AgCl) as a reduction reaction material to the reduction of 2AgCl + 2e--> 2Ag + 2Cl-to the positive electrode (6) When the seawater is introduced into the reaction reservoir, the anode 6 and the cathode 5 undergo an electrochemical reaction and are converted into electrical energy. Therefore, by outputting the electrical energy of the one section through the output terminal of the positive and negative electrodes, it can be effectively applied to general small power generators and power propellers.

When the seawater battery having the one-section electric energy as described above is arranged in series or in parallel, a larger output of electric energy can be obtained, and thus it can be applied to a large power plant.

As described above, the method and apparatus for generating electrical energy using seawater according to the present invention is that the battery device is directly converted to electrical energy after the electrochemical reaction using the seawater as an electrolyte, which replaces the existing energy As a breakthrough energy of environmental protection concept, it has great industrial use value.
