Description

Ethylene partial pressure control device and ethylene partial pressure control system including the same

[0001] The present invention relates to an ethylene partial pressure control device that controls ethylene partial pressure by generating or removing ethylene, and an ethylene partial pressure control system including the same.

[0002] Ethylene, a gas that promotes plant growth, plays a crucial role in agriculture and the food industry. When used appropriately, ethylene can enhance the growth rate and quality of crops and fruits. However, if ethylene exceeds the optimal levels required for crops and fruits, it can cause them to rot. The partial pressure of ethylene must be controlled to extend the storage and shelf life of crops and fruits, and to minimize post-harvest losses in perishable foods.

[0003] Ethylene removal technologies using oxidizers, adsorbents, and other agents can be used to control the partial pressure of ethylene. However, when using oxidizers or adsorbents, the ethylene removal process can result in a decrease in the oxidizing activity of the oxidizer or the adsorbent becoming saturated, necessitating periodic replacement. Furthermore, if a separate ethylene generating device is installed to control the partial pressure of ethylene, the miniaturization and lightweight characteristics of the ethylene partial pressure device may be compromised.

[0004] An ethylene pressure control device according to one example may include a first electrode portion extending along a plane and a second electrode portion extending along the plane and arranged to be spaced apart from the first electrode portion along a direction perpendicular to the plane.

[0005] An ethylene pressure control device according to an example may include a solid electrolyte membrane disposed between the first electrode section and the second electrode section.

[0006] An ethylene pressure control device according to an example may include a power supply unit that stores power generated between the first electrode unit and the second electrode unit, or supplies a predetermined amount of power between the first electrode unit and the second electrode unit.

[0007] An ethylene pressure control device according to an example may include a processor that controls the power supply to store power generated between the first electrode unit and the second electrode unit in a production mode for generating ethylene or a removal mode for removing ethylene, or to apply power between the first electrode unit and the second electrode unit.

[0030] The operating principle and embodiments of the present invention will be described with reference to the attached drawings below.

[0031] Fig. 1 is a front view of an ethylene partial pressure control system according to an example. Fig. 2 is a front view of an ethylene partial pressure control system with an open door according to an example. Fig. 3 is a schematic diagram of an ethylene partial pressure control system according to an example.

[0032] Referring to FIGS. 1 to 3, an ethylene partial pressure control system (1) according to an example may include a storage room (11) having a predetermined storage space and an ethylene partial pressure control device (100) capable of controlling the ethylene partial pressure inside the storage room (11). The storage room (11) may be a storage space having a predetermined volume for storing stored materials, such as vegetables or fruits, whose growth may be promoted or may cause decay depending on the ethylene partial pressure. The ethylene partial pressure control device (100) may generate ethylene to supply ethylene to the storage room (11) or remove ethylene remaining in the storage room (11). Accordingly, the ethylene partial pressure inside the storage room (11) may be controlled.

[0033] According to one example, the ethylene partial pressure control system (1) may be a refrigerator capable of cooling the stored items accommodated in the storage room (11). However, the present disclosure is not limited thereto, and the ethylene partial pressure control system (1) described in the present disclosure may be any cooling device capable of accommodating and storing stored items, such as vegetables or fruits, in the storage room (11), for example, an air conditioner, a refrigerator, a freezer, etc. For convenience of explanation, the ethylene partial pressure control system (1) according to one example is described below as being a refrigerator.

[0034] An ethylene partial pressure control system (1) according to an example can implement a refrigeration cycle that cools a specific object or space by using a refrigerant, which is a substance that changes sensitively to temperature and pressure, and generally absorbs heat at low temperature and low pressure and releases heat at high temperature and high pressure.

[0035] According to one example, the main body (5) can form the exterior of the ethylene partial pressure control system (1). The main body (5) can include a storage chamber (11) formed inside and a plurality of doors (12) for opening and closing the storage chamber (11).

[0036] The storage room (11) may be divided into multiple sections by partitions (15), and multiple shelves and storage containers may be arranged inside the storage room (11) to store food, etc. The storage room (11) may be divided into multiple sections by partitions (15). As an example, one or more ethylene partial pressure control devices (100) may be arranged depending on the location of the storage room (11) where the ethylene partial pressure is to be controlled.

[0037] For example, if the stored items contained or stored in the storage room (11) are vegetables or fruits, the vegetables or fruits may commonly generate ethylene, although the concentrations may differ. In addition, the partial pressure of ethylene within the storage room (11) may be used as an indicator of the degree of ripeness or decay of the vegetables or fruits.

[0038] As an example, if one of the plurality of compartments (11) is a fresh storage room that receives and stores stored goods such as vegetables or fruits, the ethylene partial pressure control device (100) may be disposed on one side of the storage room (11-1) to supply ethylene to the storage room (11-1) or to remove ethylene remaining in the storage room (11-1), as illustrated in FIG. 3. However, the present disclosure is not limited thereto, and if two or more of the plurality of storage rooms (11) receive stored goods such as vegetables or fruits, one or more ethylene partial pressure control devices (100) may be disposed in each of the plurality of storage rooms (11) to supply ethylene to the plurality of storage rooms (11) or to remove ethylene remaining in the plurality of storage rooms (11).

[0039] According to one example, an ethylene partial pressure control device (100) can supply ethylene to a storage chamber (11) or remove ethylene remaining in the storage chamber (11) using an electrochemical reaction. Accordingly, since an ethylene supply device for supplying ethylene and an ethylene removal device for removing ethylene do not need to be separately arranged, the ethylene partial pressure control system (1) can be made lighter and smaller. Hereinafter, an ethylene partial pressure control device (100) that supplies ethylene or removes ethylene using an electrochemical reaction will be described.

[0040] Fig. 4 is a perspective view of an ethylene partial pressure control device according to an example. Fig. 5 is a side view of an ethylene partial pressure control device according to an example.

[0041] Referring to FIGS. 4 and 5, an ethylene partial pressure control device (100) according to an example may include a first electrode unit (110), a second electrode unit (120) disposed to be spaced apart from the first electrode unit (110), a solid electrolyte membrane (130) disposed between the first electrode unit (110) and the second electrode unit (120), and a power supply unit (140) that stores power generated between the first electrode unit (110) and the second electrode unit (120) or applies a predetermined power between the first electrode unit (110) and the second electrode unit (120).

[0042] The first electrode portion (110) may include a flat plate shape extending along a plane (XZ plane). As an example, one side of the first electrode portion (110) may be arranged to contact the first gas diffusion layer (161) to be described later. In addition, the other side of the first electrode portion (110) may be arranged to face the solid electrolyte membrane (130) to be described later.

[0043] According to an example, the first electrode part (110) may include a first support and a first catalyst supported on one side of the first support. According to an example, the first catalyst may be Pt, Au, Ag, PSFNCu(Pr 0.6 Sr 0.4 Fe0.8 Nb 0.1 Cu 0.1 O 3-δ ), PBFM((PrBa) 0.95 (Fe 0.9 Mo 0.1 )2O 5+δ ), PBSCF(PrBa 0.5 Sr 0.5 Co 1.5 Fe 0.5 O5), Lanthanum Strontium Cobalt Ferrite (LSCF). However, the present disclosure is not limited thereto, and the first catalyst provided in the first electrode unit (110) may include any material capable of forming a predetermined voltage between the first catalyst and the second electrode unit (120).

[0044] The first support may include one or more of carbon black, Ketjen black, acetylene black, activated carbon powder, carbon molecular sieve, carbon nanotubes, activated carbon having micropores, mesoporous carbon, conductive polymer, or a mixture thereof.

[0045] The second electrode part (120) may include a flat plate shape extending along one plane (XZ plane). At this time, the second electrode part (120) may be arranged to be spaced apart from the first electrode part (110) by a predetermined distance along one direction (Y direction) perpendicular to the one plane (XZ plane). As an example, one surface of the second electrode part (120) may be arranged to be in contact with the second gas diffusion layer (162) to be described later. In addition, the other surface of the second electrode part (120) may be arranged to face the first electrode part (110) with the solid electrolyte membrane (130) to be described later interposed therebetween.

[0046] According to an example, the second electrode part (120) may include a second support and a second catalyst supported on one side of the second support. According to an example, the second catalyst may be Pt, Au, Ag, PSFNCu(Pr 0.6 Sr 0.4Fe 0.8 Nb 0.1 Cu 0.1 O 3-δ ), PBFM((PrBa) 0.95 (Fe 0.9 Mo 0.1 )2O 5+δ ), PBSCF(PrBa 0.5 Sr 0.5 Co 1.5 Fe 0.5 O5;), Lanthanum Strontium Cobalt Ferrite (LSCF). However, the present disclosure is not limited thereto, and the second catalyst provided in the second electrode unit (120) may include any material capable of forming a predetermined voltage between the first electrode unit (110).

[0047] The second support may include one or more of carbon black, Ketjen black, acetylene black, activated carbon powder, carbon molecular sieve, carbon nanotubes, activated carbon having micropores, mesoporous carbon, conductive polymer, or a mixture thereof.

[0048] The solid electrolyte membrane (130) is a hydrogen ion (H) generated from the first electrode part (110). + ) is a transmission channel through which the second electrode unit (120) is transmitted, and may be a polymer electrolyte membrane having hydrogen ion exchange characteristics. For example, the solid electrolyte membrane may be a sulfonated tetrafluoroethylene-based fluoropolymer-copolymer (C7HF 13 O5S·C2F4), BZCYYb(BaZr 1-x-y-z Ce x Y y Yb z O 3-δ, where x, y, and z are dopant levels between 0 and 1 and x+y+z <1, and δ is oxygen ion deficiency). As described above, by arranging the solid electrolyte membrane (130) between the first electrode part (110) and the second electrode part (120), unlike the liquid electrolyte, the need for separate filling is eliminated, thereby improving the convenience of use.

[0049] According to an example, the solid electrolyte membrane (130) generates hydrogen ions (H) from the first electrode portion (110). + ) can provide a path for the hydrogen ions (H) to pass through the solid electrolyte membrane (130) and move to the second electrode unit (120). Therefore, the solid electrolyte membrane (130) according to an example may be a cation exchange resin membrane. For example, the solid electrolyte membrane (130) is a polymer, which is a high molecular compound, and hydrogen ions (H + ) can contribute to lowering the resistance by increasing the mobility of hydrogen ions (H). As described above, the solid electrolyte membrane (130) disposed between the first electrode part (110) and the second electrode part (120) can + ) contributes to lowering the resistance by increasing the mobility of the catalyst, thereby enabling faster implementation of ethylene removal and ethylene production reactions. In addition, the power required for the ethylene removal and ethylene production reactions can be reduced.

[0050] According to an example, the thickness of the solid electrolyte membrane (130) is, for example, 5 µm or more and 300 µm or less, 10 µm or more and 200 µm or less, or 15 µm or less and 100 µm or less. In this case, if the thickness of the solid electrolyte membrane (130) is less than 5 µm, the mechanical strength may be lowered, the chemical stability may be lowered, and if it exceeds 300 µm, the electrical resistance may be increased.

[0051] In order to form a membrane-electrode assembly, bonding of a first electrode part (110), a second electrode part (120), and a solid electrolyte membrane (130) is required, and such bonding can be performed by a heat-pressure method or the like. For example, using hot press equipment, a heat-pressure bonding process can be performed at a temperature of 120 to 150°C for 0.1 to 10 minutes and a pressure of 50 to 200 kgf / c㎠.

[0052] The first gas diffusion layer (161) can serve to enable the reaction gas to easily access the catalyst provided in the first electrode unit (110). According to one example, the first gas diffusion layer (161) can be provided in a plate shape extending along one plane and arranged to contact one surface of the first electrode unit (110).

[0053] According to an example, the first gas diffusion layer (161) may include a porous material so that the reaction gas can move to the catalyst provided in the first electrode unit (110). For example, the first gas diffusion layer (161) may include carbon paper, carbon cloth, or a metal plate in a mesh shape. The metal plate in a mesh shape may be a stainless steel mesh, a titanium mesh, or a nickel mesh. However, the present disclosure is not limited thereto, and the first gas diffusion layer (161) may include any material through which the reaction gas can pass.

[0054] The second gas diffusion layer (162) can play a role in allowing the reaction gas to easily access the catalyst provided in the second electrode unit (120). According to one example, the second gas diffusion layer (162) can be provided in a plate shape extending along one plane and arranged to contact one surface of the second electrode unit (120).

[0055] According to an example, the second gas diffusion layer (162) may include a porous material so that the reaction gas can move to the catalyst provided in the second electrode unit (120). For example, the second gas diffusion layer (162) may include carbon paper, carbon cloth, or a metal plate in a mesh shape. The metal plate in a mesh shape may be a stainless steel mesh, a titanium mesh, or a nickel mesh. However, the present disclosure is not limited thereto, and the first gas diffusion layer (162) may include any material through which the reaction gas can pass.

[0056] The first support plate (171) is disposed on one side of the first gas diffusion layer (161) and can support the first electrode unit (110) together with the second support plate (172) to be described later. According to an example, a supply path (1710) through which a reactant supplied to the first electrode unit (110) can be introduced may be disposed on the other side of the first support plate (171). As an example, a reactant storage tank, for example, an oxygen tank (300; see FIG. 6) or a water tank (400; see FIG. 7), may be connected to the supply path (1710) to supply oxygen or moisture (H2O). In the present specification, moisture (H2O) may refer not only to a liquid state but also to a liquid-gas mixture state. At this time, the supply speed of oxygen or moisture can be adjusted by adjusting the pressure of the oxygen tank (300) or the water tank (400). Additionally, a discharge path (1711) through which a product generated from the first electrode portion (110) can be discharged may be arranged on the other side of the first support plate (171). However, the present disclosure is not limited thereto, and when the reactant is in a gaseous form, an opening-shaped supply path and discharge path through which the reactant can flow into the first gas diffusion layer (161) may be formed.

[0057] The second support plate (172) is arranged on one surface of the second gas diffusion layer (162) and can support the second electrode portion (120). According to one example, the first gas diffusion layer (161), the first electrode portion (110), the solid electrolyte membrane (130), the second electrode portion (120), and the second gas diffusion layer (162) can be sequentially arranged between the first support plate (171) and the second support plate (172).

[0058] According to an example, an opening (1720) may be arranged on one surface of the second support plate (172) through which a reactant supplied to the second electrode unit (120) may be introduced and a product generated from the second electrode unit (120) may be discharged. As an example, in the ethylene removal mode as illustrated in FIG. 6, ethylene gas may be introduced and removed through the opening (1720) provided in the second electrode unit (120). In addition, in the ethylene production mode as illustrated in FIG. 7, ethylene gas may be discharged and generated through the opening (1720) provided in the second electrode unit (120). That is, ethylene disposed in a target space for adjusting the partial pressure of ethylene, for example, a storage room (11), may be introduced through the opening (1720), or ethylene may be discharged into the storage room (11) through the opening (1720). Below, the ethylene removal mode and ethylene production mode for removing or producing ethylene using the ethylene partial pressure control device (100) are described.

[0059] Fig. 6 is a side view of an ethylene partial pressure control device in an ethylene removal mode according to an example. Fig. 7 is a side view of an ethylene partial pressure control device in an ethylene production mode according to an example.

[0060] As described above, the ethylene partial pressure control device (100) according to an example can generate or remove ethylene using an electrochemical reaction. Hereinafter, a state in which ethylene is removed using the ethylene partial pressure control device (100) is referred to as a removal mode, and a state in which ethylene is generated using the ethylene partial pressure control device (100) is referred to as a production mode.

[0061] Referring to FIG. 6, in a removal mode for removing ethylene using an ethylene partial pressure control device (100) according to an example, oxygen (O2) may be supplied to the first electrode unit (110). For example, oxygen (O2) stored in an oxygen tank (300) may be delivered to the first gas diffusion layer (161) through a supply path (1710) provided in the first support plate (171). The oxygen (O2) delivered to the first gas diffusion layer (161) may pass through the first gas diffusion layer (161) and be supplied to the first electrode unit (110).

[0062] In addition, in a removal mode in which ethylene is removed using an ethylene partial pressure control device (100), moisture (H2O) and ethylene (C2H4) may be supplied to the second electrode unit (120). According to one example, the external space in which moisture (H2O) and ethylene (C2H4) are supplied to the second electrode unit (120) may be a partial pressure control space in which the partial pressure of ethylene must be controlled, for example, a storage room (11-1) as illustrated in FIG. 3.

[0063] According to one example, moisture (H2O) and ethylene (C2H4) placed in a pressure control space can be transferred to a second gas diffusion layer (162) through an opening (1720) provided in a second support plate (172). The moisture (H2O) and ethylene (C2H4) transferred to the second gas diffusion layer (162) can pass through the second gas diffusion layer (162) and be supplied to the second electrode unit (120).

[0064] As an example, if the target space where the partial pressure of ethylene is to be controlled is a storage room (11-1) having a predetermined receiving space as illustrated in FIG. 3, moisture (H2O) and ethylene (C2H4) placed in the storage room (11-1) can be introduced through an opening (1720) provided in the second support plate (172) through natural circulation. However, the present disclosure is not limited thereto, and in order to increase the rate of decrease in the partial pressure of ethylene, a fan (not shown) may be placed inside the storage room (11-1) to forcibly supply moisture (H2O) and ethylene (C2H4) to the opening (1720) provided in the second support plate (172).

[0065] As described above, when oxygen (O2) is supplied to the first electrode unit (110), the following reaction may occur in the first electrode unit (110) to produce moisture (H2O). In addition, when moisture (H2O) and ethylene (C2H4) are supplied to the second electrode unit (120), the following reaction may occur in the second electrode unit (120) to produce carbon dioxide (CO2). At this time, the first electrode unit (110) may function as a cathode, and the second electrode unit (120) may function as an anode.

[0070] Overall reaction equation:

[0071]

[0072] As can be seen from the overall reaction formula above, in the case of the removal mode for removing ethylene, ethylene (C2H4) and oxygen (O2) may be supplied and carbon dioxide (CO2) and moisture (H2O) may be generated in the overall reaction of the ethylene partial pressure control device (100). In other words, the ethylene partial pressure control device (100) according to an example may remove ethylene (C2H4) and oxygen (O2) and generate carbon dioxide (CO2) and moisture (H2O) in the ethylene removal mode. At this time, a predetermined power may be generated between the first electrode unit (110) and the second electrode unit (120) and stored in the power supply unit (140). The processor (190) according to an example may control the power supply unit (140) so that the predetermined power generated between the first electrode unit (110) and the second electrode unit (120) is stored in the power supply unit (140), thereby implementing the removal mode for removing ethylene.

[0073] Also, referring to FIG. 7, in a production mode for producing ethylene using an ethylene partial pressure control device (100) according to an example, moisture (H2O) may be supplied to the first electrode unit (110). For example, moisture (H2O) stored in a water tank (400) may be delivered to the first gas diffusion layer (161) through a supply path (1710) provided in the first support plate (171). The moisture (H2O) delivered to the first gas diffusion layer (161) may pass through the first gas diffusion layer (161) and be supplied to the first electrode unit (110).

[0074] Additionally, in a production mode in which ethylene is produced using an ethylene partial pressure control device (100), carbon dioxide (CO2) may be supplied to the second electrode unit (120). According to one example, the external space in which carbon dioxide (CO2) is supplied to the second electrode unit (120) may be a partial pressure control space in which the partial pressure of ethylene must be controlled, for example, a storage room (11-1) as illustrated in FIG. 3.

[0075] According to one example, carbon dioxide (CO2) placed in a partial pressure control space where the partial pressure of ethylene is to be controlled can be delivered to a second gas diffusion layer (162) through an opening (1720) provided in a second support plate (172). The carbon dioxide (CO2) delivered to the second gas diffusion layer (162) can pass through the second gas diffusion layer (162) and be supplied to the second electrode unit (120).

[0076] For example, if the partial pressure control space where the partial pressure of ethylene is to be controlled is a storage room (11-1) having a predetermined receiving space as illustrated in FIG. 3, carbon dioxide (CO2) placed in the storage room (11-1) can be introduced through an opening (1720) provided in the second support plate (172) through natural circulation. However, the present disclosure is not limited thereto, and in order to increase the partial pressure increase rate of ethylene, a fan (not shown) may be placed inside the storage room (11-1) to forcibly supply carbon dioxide (CO2) to the opening (1720) provided in the second support plate (172), or a separate carbon dioxide tank (600; see FIG. 10) may be connected to supply carbon dioxide (CO2) to the second electrode unit (120).

[0077] As described above, when moisture (H2O) is supplied to the first electrode unit (110), the following reaction may occur in the first electrode unit (110) to produce oxygen (O2). In addition, when carbon dioxide (CO2) is supplied to the second electrode unit (120), the following reaction may occur in the second electrode unit (120) to produce moisture (H2O) and ethylene (C2H4). At this time, the first electrode unit (110) may function as an anode, and the second electrode unit (120) may function as a cathode.

[0083]

[0084] As can be seen from the overall reaction formula above, in the case of the production mode for generating ethylene, in the overall reaction of the ethylene partial pressure control device (100), carbon dioxide (CO2) and moisture (H2O) are supplied, and ethylene (C2H4) and oxygen (O2) can be generated. In other words, in the ethylene partial pressure control device (100) according to an example, when carbon dioxide (CO2) and moisture (H2O) are supplied in the ethylene production mode, ethylene (C2H4) and oxygen (O2) can be generated. At this time, the power supply unit (140) can supply a predetermined power between the first electrode unit (110) and the second electrode unit (120). The processor (190) according to an example can control the power supply unit (140) to supply a predetermined power between the first electrode unit (110) and the second electrode unit (120), thereby implementing the production mode for generating ethylene.

[0085] Fig. 8 is a side view of an ethylene partial pressure control device in an ethylene removal mode according to an example. Fig. 9 is a side view of an ethylene partial pressure control device in an ethylene production mode according to an example.

[0086] Referring to FIG. 8, in a removal mode for removing ethylene using an ethylene partial pressure control device (100) according to an example, moisture (H2O) may be supplied to the first electrode unit (110). For example, moisture (H2O) stored in a water tank (400) may be delivered to the first gas diffusion layer (161) through a supply path (1710) provided in the first support plate (171). The moisture (H2O) delivered to the first gas diffusion layer (161) may pass through the first gas diffusion layer (161) and be supplied to the first electrode unit (110).

[0087] In addition, in a removal mode in which ethylene is removed using an ethylene partial pressure control device (100), ethylene (C2H4) may be supplied to the second electrode unit (120). According to one example, the external space in which ethylene (C2H4) is supplied to the second electrode unit (120) may be a partial pressure control space in which the partial pressure of ethylene must be controlled, for example, a storage room (11-1) as illustrated in FIG. 3.

[0088] According to one example, ethylene (C2H4) placed in a pressure control space can be delivered to a second gas diffusion layer (162) through an opening (1720) provided in a second support plate (172). The ethylene (C2H4) delivered to the second gas diffusion layer (162) can pass through the second gas diffusion layer (162) and be supplied to the second electrode unit (120).

[0089] As an example, if the target space where the partial pressure of ethylene is to be controlled is a storage room (11-1) having a predetermined receiving space as illustrated in FIG. 3, ethylene (C2H4) placed in the storage room (11-1) can be introduced through an opening (1720) provided in the second support plate (172) through natural circulation. However, the present disclosure is not limited thereto, and in order to increase the rate of decrease in the partial pressure of ethylene, a fan (not illustrated) may be placed inside the storage room (11-1) to forcibly supply ethylene (C2H4) to the opening (1720) provided in the second support plate (172).

[0090] As described above, when moisture (H2O) is supplied to the first electrode unit (110), the following reaction may occur in the first electrode unit (110) to produce oxygen (O2). In addition, when ethylene (C2H4) is supplied to the second electrode unit (120), the following reaction may occur in the second electrode unit (120) to produce ethane (C2H6). At this time, the first electrode unit (110) may function as an anode, and the second electrode unit (120) may function as a cathode.

[0095] Overall reaction equation:

[0096]

[0097] As can be seen from the overall reaction formula above, in the removal mode for removing ethylene, ethylene (C2H4) and moisture (H2O) are supplied and ethane (C2H6) and oxygen (O2) can be generated in the overall reaction of the ethylene partial pressure control device (100). In other words, the ethylene partial pressure control device (100) according to an example can remove ethylene (C2H4) and moisture (H2O) and generate ethane (C2H6) and oxygen (O2) in the ethylene removal mode. At this time, the power supply unit (140) can supply a predetermined amount of power between the first electrode unit (110) and the second electrode unit (120). According to an example, a processor (190) can control a power supply unit (140) to supply a predetermined amount of power between a first electrode unit (110) and a second electrode unit (120) so that the power supply unit (140) stores the power, thereby implementing a removal mode for removing ethylene.

[0098] Also, referring to FIG. 9, in a production mode for producing ethylene using an ethylene partial pressure control device (100) according to an example, oxygen (O2) may be supplied to the first electrode unit (110). For example, oxygen (O2) stored in an oxygen tank (300) may be delivered to the first gas diffusion layer (161) through a supply path (1710) provided in the first support plate (171). The oxygen (O2) delivered to the first gas diffusion layer (161) may pass through the first gas diffusion layer (161) and be supplied to the first electrode unit (110).

[0099] Additionally, in a production mode in which ethylene is produced using an ethylene partial pressure control device (100), ethane (C2H6) may be supplied to the second electrode unit (120). For example, ethane (C2H6) placed externally may be delivered to the second gas diffusion layer (162) through an opening (1720) provided in the second support plate (172). The ethane (C2H6) delivered to the second gas diffusion layer (162) may be supplied to the second electrode unit (120) through the second gas diffusion layer (162). However, the present disclosure is not limited thereto, and in order to increase the rate of increase in the partial pressure of ethylene, a fan (not shown) may be placed inside the storage chamber (11-1) to forcibly supply ethane (C2H6) to an opening (1720) provided in the second support plate (172), or a separate ethane tank (500; see FIG. 10) may be connected to supply carbon dioxide (CO2) to the second electrode unit (120).

[0100] As described above, when oxygen (O2) is supplied to the first electrode unit (110), the following reaction may occur in the first electrode unit (110) to produce moisture (H2O). In addition, when ethane (C2H6) is supplied to the second electrode unit (120), the following reaction may occur in the second electrode unit (120) to produce ethylene (C2H4). At this time, the first electrode unit (110) may function as a cathode, and the second electrode unit (120) may function as an anode.

[0103] Second electrode section:

[0104]

[0105] Overall reaction equation:

[0106]

[0107] As can be seen from the overall reaction formula above, in the production mode for generating ethylene, in the overall reaction of the ethylene partial pressure control device (100), ethane (C2H6) and oxygen (O2) are supplied, and ethylene (C2H4) and moisture (H2O) can be generated. In other words, in the ethylene partial pressure control device (100) according to an example, when ethane (C2H6) and oxygen (O2) are supplied in the ethylene production mode, ethylene (C2H4) and moisture (H2O) can be generated. At this time, a predetermined amount of power can be generated between the first electrode unit (110) and the second electrode unit (120) and stored in the power supply unit (140). According to an example, a processor (190) can control a power supply (140) so that a predetermined amount of power generated between a first electrode unit (110) and a second electrode unit (120) is stored in the power supply unit (140), thereby implementing a production mode for generating ethylene.

[0108] As described above and as illustrated in FIGS. 6 to 9, the ethylene partial pressure control device (100) according to an example can operate in response to various external environments by differently setting the steps of supplying different reactants, supplying power, or generating power to the first electrode unit (110) and the second electrode unit (120) in the ethylene removal and ethylene production modes. Although the above-described examples disclose the production and removal of ethylene, the present disclosure is not limited thereto, and different substances, such as formaldehyde and carbon dioxide, may be generated or removed depending on the type of reactant and the magnitude of power supplied to the first electrode unit (110) and the second electrode unit (120).

[0109] Fig. 10 is a block diagram of an ethylene partial pressure control system according to an example. Fig. 11 is a schematic diagram of a storage room in which a storage material is stored according to an example.

[0110] Referring to FIGS. 10 and 11, an ethylene partial pressure control system (1) according to an example may further include a sensor unit (700). As described above, when the stored material (T) accommodated or stored in the storage room (11-1) is a vegetable or a fruit, the vegetables or fruits can commonly generate ethylene, although there is a difference in concentration. In addition, the partial pressure of ethylene inside the storage room (11-1) can be used as an indicator of the degree of ripeness or decay of the vegetable or fruit. Therefore, by detecting the partial pressure of ethylene inside the storage room (11-1), the degree of ripeness or decay of the stored material (T), for example, a vegetable or a fruit, accommodated or stored in the storage room (11-1) can be confirmed.

[0111] As an example, the sensor unit (700) can detect the ethylene partial pressure of the storage room (11-1) where the stored material (T) is stored. According to one example, the sensor unit (700) can include a sensing unit that detects the acidity value (potential of hydrogen; pH) that changes in response to the change in the ethylene partial pressure of the storage room (11-1). However, the present disclosure is not limited thereto. For example, it goes without saying that any sensing unit capable of detecting a change in the partial pressure of ethylene can be used as the sensor unit (700).

[0112] For example, if the storage room (11-1) is a fresh storage room that receives and stores a storage item (T) such as a vegetable or fruit, the sensor unit (700) may be provided in a single or multiple units and placed inside the storage room (11-1). For example, if the storage item (T) such as a vegetable or fruit is placed in a specific area of ​​the storage room (11-1), the sensor unit (700) may be provided in a single unit and may detect the ethylene partial pressure of the specific area of ​​the storage room (11-1). As another example, if the storage item (T) such as a vegetable or fruit is placed in an arbitrary area of ​​the storage room (11-1), the sensor unit (700) may be provided in a multiple unit and placed in the storage room (11-1) so as to be spaced apart from each other by a predetermined interval, thereby detecting the ethylene partial pressure of the entire space of the storage room (11-1).

[0113] As an example, the camera (800) can acquire an image of a storage item (T) accommodated and stored in the storage room (11-1). For example, if the storage item (T) accommodated and stored in the storage room (11-1) is a vegetable or a fruit, the camera (800) can acquire an image of the vegetable or fruit. According to an example, the camera (800) can include an internal camera for taking pictures of the inside of the storage room (11-1).

[0114] The processor (190) can control the camera (800) to take pictures when a specific event is detected. For example, the processor (190) can control the camera (800) to take pictures when a door is opened and then closed. As another example, the processor (190) can control the camera (800) to take pictures at regular intervals (e.g., once every 30 minutes).

[0115] The memory (900) can store images (still images or moving images) captured by the camera (800). In addition, the memory (900) can store various types of comparative images for comparison with the captured images. For example, if the stored object (T) is a food such as a vegetable or a fruit, the various types of comparative food images can include many (for example, dozens to hundreds) food images for each type of food. If the captured image includes an apple, the captured image can be compared with a comparative food image including various images of carrots in various shapes, sizes, colors, washing states, or whether they are packaged.

[0116] The storage object recognition module (1000) is stored in the memory (900) and is executed by the processor (190) to identify at least one storage object (T) in an image. For example, if the storage object (T) stored in the storage room (11) is a food such as a vegetable or a fruit, the storage object recognition module (1000) can identify at least one food in an image captured by the camera (800) (identify the type of food) and recognize the state of the identified food (degree of ripeness of the food).

[0117] The storage object recognition module (1000) can identify each food item within an image by utilizing an image segmentation algorithm that identifies (or distinguishes) an object from the background in the image. In this case, the module may include an artificial intelligence model trained to identify at least one food item within the image. This model may be a model trained to have a standard for identifying an object from the background in the image. In addition, the storage object recognition module (1000) can recognize food items using an artificial intelligence model trained to recognize food items based on food images. For example, this model may be trained using various apple images with different shapes, sizes, colors, washing conditions, or packaging status as training data to recognize the degree of ripeness of the apple.

[0118] As described above, the storage recognition module (1000) can recognize the type and state of the storage (T) stored in the storage room (11-1), for example, the degree of maturation of the storage (T). In addition, the sensor unit (700) can detect the ethylene partial pressure of the storage room (11-1). Accordingly, the processor (190) can control the power unit (140) to generate or remove ethylene according to the type and state of the storage (T) identified by the storage recognition module (1000) and the detected ethylene partial pressure of the storage room (11-1).

[0119] As an example, the processor (190) may control the power supply unit (140) so that a predetermined power generated between the first electrode unit (110) and the second electrode unit (120) is stored in the power supply unit (140), or control the power supply unit (140) to supply a predetermined power between the first electrode unit (110) and the second electrode unit (120), as shown in FIGS. 6 to 9, according to the type and state of the storage unit (T) identified by the storage unit recognition module (1000) and the ethylene partial pressure of the detected storage room (11-1), to implement a production mode for generating ethylene or a removal mode for removing ethylene.

[0120] In addition, the processor (190) according to an example can control one or more of the reactant supply units (G) supplied to the first electrode unit (110) and the second electrode unit (120), for example, an oxygen tank (300), a water tank (400), an ethane tank (500), or a carbon dioxide tank (600), to increase or decrease the reaction speed for producing or removing ethylene. As an example, according to the state of the storage (T) identified by the storage recognition module (1000), for example, the degree of ripening of the fruit, the processor (190) can adjust the supply speed of the reactant supplied from the reactant supply unit (G) to increase or decrease the production speed or removal speed of ethylene, thereby controlling the ripening speed of the fruit.

[0121] Figure 12 is a flow chart of an operating method of an ethylene partial pressure control system according to an example.

[0122] Referring to FIG. 12, the operating method of the ethylene partial pressure control system according to an example may include a step of photographing the stored object. (S110) As an example, when a user stores the stored object in the storage room (11-1), the camera (800) may obtain an image of the stored object (T) accommodated and stored in the storage room (11-1). For example, when the stored object (T) accommodated and stored in the storage room (11-1) is a vegetable or a fruit, the camera (800) may obtain an image of the vegetable or the fruit. The camera (800) according to an example may include an internal camera for photographing the inside of the storage room (11-1).

[0123] Next, a step of identifying the type of storage and recognizing the state of the storage may be included. (S120) As an example, the storage recognition module (1000) can identify the type of storage, for example, the type of food, from an image captured by the camera (192), and recognize the state of the identified storage, for example, the degree of ripening of the food.

[0124] Next, a step of detecting the partial pressure of ethylene in the storage room may be included. (S130) As an example, the sensor unit (700) may detect the partial pressure of ethylene in the storage room (11-1) where the stored material is stored. As an example, if the stored material received or stored in the storage room (11-1) is a vegetable or a fruit, the vegetable or fruit may commonly generate ethylene, although there may be differences in concentration. In addition, the partial pressure of ethylene inside the storage room (11-1) may be used as an indicator of the degree of ripeness or decay of the vegetable or fruit. Therefore, the sensor unit (700) may detect the partial pressure of ethylene in the storage room (11-1) where the stored material is stored, in order to confirm the degree of ripeness or decay of the stored material.

[0125] Next, a step of controlling an ethylene partial pressure control device to generate or remove ethylene according to the ethylene partial pressure of the detected storage room and the type and state of the identified storage. (S140) An ethylene partial pressure control device (100) according to an example can implement a production mode for generating ethylene or a removal mode for removing ethylene according to the type and state of the storage identified by the storage recognition module (1000) and the ethylene partial pressure of the detected storage room (11-1).
