A first preferred embodiment of the electrolytic hydrogen and oxygen generation device 100

[0032] Figure 1 FIG. 1 is a cross-sectional diagram of a first preferred embodiment of the present application, a device 100 for generating hydrogen and oxygen by electrolysis. Figure 1 As shown, the device 100 for generating hydrogen and oxygen by electrolysis includes two separators 111 and an electrolysis unit sandwiched between the two separators 111 .

[0033] The electrolysis unit includes a positive electrode plate 121 , a proton membrane 130 , a negative electrode plate 122 , a first porous conductive structure 141 , a second porous conductive structure 142 , a first isolation frame 151 , a second isolation frame 152 , and a reaction water flow channel 160 .

[0034] Two separators 111 are arranged on the outermost sides of the device 100 for generating hydrogen and oxygen by electrolysis, that is, the first separator 111 is arranged on the other side of the positive electrode plate 121 relative to the first isolation frame 151, and the other separator 112 is arranged on the other side of the negative electrode plate 122 relative to the second isolation frame 152. The function of the separator 111 is to isolate the positive electrode plate 121 and the negative electrode plate 122 from the outside world, so the separator 111 can be a single insulating plate or a composite structure including insulating materials, which is not limited in this embodiment.

[0035] In the traditional electrolysis process, the electrolyte between the positive plate and the negative plate is not pure water, but an electrolyte with strong alkali added. Because pure water has high impedance and poor conductivity, the strong alkali is ionized in water to carry electrons and make the electrolyte conductive, thus generating a water electrolysis reaction. However, the electrolyte often vaporizes with the water electrolysis reaction and mixes into the hydrogen and oxygen generated by electrolysis. This hydrogen and oxygen have adverse side effects on electromechanical equipment, food, and the human body.

[0036] In this embodiment, the water required for the electrolysis reaction (hereinafter referred to as reaction water) is mainly pure water, rather than a conventional electrolyte. Therefore, there is no electrolyte between the positive plate 121 and the negative plate 122, but rather a first isolation frame 151, a first porous conductive structure 141, a proton membrane 130, a second porous conductive structure 142, a second isolation frame 152 and other components. The purpose is to form a conductive path to electrolyze the reaction water, and to separate and take out the pure hydrogen and oxygen generated by the electrolysis of the reaction water.

[0037] In order to achieve the above purpose, the first isolation frame 151 is arranged between the positive plate 121 and the proton membrane 130, and a first space 1511 is formed inside. The first porous conductive structure 141 is filled in the first space 1511, one function is to conduct electricity, and the other function is to fill the reaction water in the pores so that the reaction water can be electrolyzed. The second isolation frame 152 is arranged between the negative plate 122 and the proton membrane 130, and a second space 1521 is formed inside. The second porous conductive structure 142 is filled in the second space 1521, one function is to conduct electricity, and the other function is to fill the reaction water in the pores so that the reaction water can be electrolyzed. In a preferred embodiment, the first porous conductive structure 141 and the second porous conductive structure 142 preferably use porous nickel. Porous nickel has a network structure of interconnected metal nickel material entities and pores, the pores are interconnected, light, conductive, and air-permeable and water-permeable between the pores.

[0038] The proton membrane 130 is a polymer membrane, generally with a thickness of 15 to 250 microns, and a porous structure, but the pore size is very small, which allows electrons and small molecules to pass through, such as hydrogen, water, etc., but large molecules cannot pass through. The proton membrane 130 is arranged between the first porous conductive structure 141 and the second porous conductive structure 142, and the two sides of the membrane are also covered with a catalyst. When the positive plate 121 and the negative plate 122 are energized, and the reaction water fills the first porous conductive structure 141 and the second porous conductive structure 142, the water molecules can pass through the proton membrane 130, so a conductive circuit can be formed for electrolysis. During electrolysis, oxygen is generated in the positive plate 121 and hydrogen is generated in the negative plate 122. Since the proton membrane 130 can only pass small molecules, the oxygen generated by the positive plate 121 cannot pass through the proton membrane 130 to reach the second porous conductive structure 142, and can only stay in the positive plate 121 and the first porous conductive structure 141. Even though part of the hydrogen can pass through the proton membrane 130 and reach the first porous conductive structure 141 , only hydrogen and reaction water are present in the second porous conductive structure 142 and the negative electrode plate 122 . Thus, this embodiment can provide pure hydrogen output without gasified electrolyte.

[0039] In order to improve the electrolysis efficiency and protect the proton membrane 130, the cross-sectional areas of the first porous conductive structure 141 and the second porous conductive structure 142 are not less than the area of ​​the proton membrane 130. In other words, the two sides of the proton membrane 130 are completely covered by the first porous conductive structure 141 and the second porous conductive structure 142, so during the electrolysis process, the reaction water can completely penetrate the two sides of the proton membrane 130, thereby preventing the proton membrane 130 from being burned during the electrolysis process.

[0040] In order to introduce the reaction water into the electrolytic hydrogen and oxygen generation device 100, the positive electrode plate 121 is further provided with a first water inlet channel 1211 connected to the first porous conductive structure 141; the negative electrode plate 122 is further provided with a second water inlet channel 1221 connected to the second porous conductive structure 142; the reaction water channel 160 connects the first water inlet channel 1211 and the second water inlet channel 1221. In this way, the reaction water enters the first porous conductive structure 141 and the second porous conductive structure 142 respectively along the first water inlet channel 1211 and the second water inlet channel 1221.

[0041] The volume expansion ratio of liquid hydrogen to gaseous hydrogen is 851 times, and the volume expansion ratio of liquid oxygen to gaseous oxygen is 860 times. Therefore, two water molecules generate two hydrogen molecules and one oxygen molecule through electrolysis, and the volume expansion exceeds 1200 times. A corresponding structure must be provided to guide the oxygen and hydrogen generated by electrolysis. In this embodiment, the positive plate 121 is also provided with a water-oxygen flow channel 1212, and the negative plate 122 is also provided with a water-hydrogen flow channel 1222. The oxygen and reaction water generated by electrolysis can be guided out along the water-oxygen flow channel 1212, and the hydrogen and reaction water generated by electrolysis can be guided out along the water-hydrogen flow channel 1222. Furthermore, because the gas has a large volume and a light weight, the position of the water-oxygen flow channel 1212 for guiding out oxygen is higher than the first water inlet flow channel 1211, and the position of the water-hydrogen flow channel 1222 for guiding out hydrogen is higher than the second water inlet flow channel 1221.

[0042] The reaction water is introduced into the electrolysis hydrogen and oxygen generating device 100, and the hydrogen and oxygen generated by electrolysis are further exported from the electrolysis hydrogen and oxygen generating device 100, so the electrolysis hydrogen and oxygen generating device is also provided with a reaction water inlet 161, a water oxygen outlet 163, and a water hydrogen outlet 164. The reaction water inlet 161 is connected to the reaction water flow channel 160, and is used to introduce the external reaction water into the electrolysis hydrogen and oxygen generating device 100. The water oxygen outlet 163 is connected to the water oxygen flow channel 1212, and the water hydrogen outlet 164 is connected to the water hydrogen flow channel 1222, and is used to export the hydrogen and oxygen generated by electrolysis from the electrolysis hydrogen and oxygen generating device 100. Preferably, the reaction water inlet 161, the water oxygen outlet 163, and the water hydrogen outlet 164 are set on the isolation plate 111, and the three can be set on a certain isolation plate 111 at the same time, or can be set separately on different isolation plates 111, depending on the actual space limitations or requirements.

[0043] Considering better oxygen and hydrogen extraction efficiency, the positions of the water-oxygen outlet 163 and the water-hydrogen outlet 164 are not lower than the water-oxygen flow channel 1212 and the water-hydrogen flow channel 1222 , respectively, and are both higher than the position of the reaction water inlet 161 .

[0044] In this embodiment, the reaction water enters the electrolytic hydrogen and oxygen generation device 100 from the reaction water inlet 161, and enters the first porous conductive structure 141 and the second porous conductive structure 142 respectively through the reaction water flow channel 160, the first water inlet flow channel 1211 and the second water inlet flow channel 1221. When the positive electrode plate 121 and the negative electrode plate 122 are energized for electrolysis, hydrogen is generated in the negative electrode plate 122, and oxygen is generated in the positive electrode plate 121. Due to the action of the proton membrane 130, the oxygen generated by the positive electrode plate 121 will be retained on the side of the positive electrode plate 121 and the first porous conductive structure 141, and will be led out of the electrolytic hydrogen and oxygen generation device 100 through the water-oxygen flow channel 1221 and the water-oxygen outlet 163; the hydrogen generated by the negative electrode plate 122 will be retained on the side of the negative electrode plate 122 and the second porous conductive structure 142, and will be led out of the electrolytic hydrogen and oxygen generation device 100 through the water-hydrogen flow channel 1222 and the water-hydrogen outlet 164.

[0045] Furthermore, a dehumidifier or a water filter for filtering out the reaction water may be respectively provided at the water-oxygen outlet 163 and the water-hydrogen outlet 164, so that the output of pure hydrogen and pure oxygen can be obtained.

[0046] Second preferred embodiment

[0047] Please see Figure 2 The present application further proposes a second preferred embodiment, which is an electrolytic hydrogen and oxygen generation device 200, comprising two isolation plates 111, and a plurality of electrolytic units connected in series and clamped between the two isolation plates 111, and an intermediate isolation plate 201 is also arranged between each electrolytic unit.

The features of each electrolytic unit are as described in the first preferred embodiment above, and will not be repeated here.

[0049] The positive electrode plate 121 includes a first water inlet channel 1211 and a water-oxygen channel 1212, the first water inlet channel 1211 and the water-oxygen channel 1212 are connected to the first porous conductive structure 141, the negative electrode plate 122 includes a second water inlet channel 1221 and a water-hydrogen channel 1222, the second water inlet channel 1221 and the water-hydrogen channel 1222 are connected to the second porous conductive structure 142, and the reaction water channel 160 connects the first water inlet channel 1211 and the second water inlet channel 1221.

[0050] The reaction water flow channels 160 of each electrolysis unit are interconnected, the water-oxygen flow channels 1212 of each electrolysis unit are interconnected, and the water-hydrogen flow channels 1222 of each electrolysis unit are interconnected.

[0051] The electrolytic hydrogen and oxygen generation device 200 also includes a reaction water inlet 161, a water oxygen outlet 163, and a water hydrogen outlet 164. The reaction water inlet 161 is connected to the reaction water flow channel 160, and is used to introduce external reaction water into the electrolytic hydrogen and oxygen generation device 100. The water oxygen outlet 163 is connected to the water oxygen flow channel 1212, and the water hydrogen outlet 164 is connected to the water hydrogen flow channel 1222, and is used to lead the hydrogen and oxygen generated by electrolysis out of the electrolytic hydrogen and oxygen generation device 100. The reaction water inlet 161, the water oxygen outlet 163, and the water hydrogen outlet 164 can be set at the same time on a certain isolation plate 111 or on different isolation plates, depending on the actual space limitations or requirements.

[0052] By connecting a plurality of electrolysis units in series, the device 200 for generating hydrogen and oxygen by electrolysis provided in this embodiment can improve the efficiency of generating hydrogen and oxygen by electrolysis.
