[0018] The beneficial technical effects of the present utility model:

[0019] An oxygen generation device provided by the present utility model connects a hydrogen fuel cell and a proton exchange membrane electrolytic water oxygen generator together through a first pipeline. Water is added to the proton exchange membrane electrolytic water oxygen generator through a water injection port. External power drives the proton exchange membrane electrolytic water oxygen generator to electrolyze water through the proton exchange membrane electrolytic water oxygen generator and an external power supply I to generate oxygen and hydrogen respectively. Among them, oxygen is output through an oxygen channel for standby, and the generated hydrogen is supplied to the hydrogen fuel cell for power generation through the first pipeline. The hydrogen fuel cell generates power by mixing the air entering through the mixing channel and the hydrogen entering through the first pipeline. The generated power is used by the proton exchange membrane electrolytic water oxygen generator through an external power supply III and a negative electrode power connection port I. In this way, the power consumption for power generation is greatly reduced. At the same time, the by-product water generated during the power generation process of the hydrogen fuel cell returns to the proton exchange membrane electrolytic water oxygen generator through a second pipeline. In this way, the water consumption is greatly reduced. Theoretically speaking, in the whole reaction process, water is not consumed, which further reduces the cost. In an ideal process, no power is consumed either. The whole reaction process is only a process of displacing oxygen with water and power as the medium;

[0020] In this way, the process of absolute power consumption and water consumption in the principle generation process becomes a compensation activity for compensating the non-ideality of the whole system, and the operation cost and maintenance cost are greatly reduced;

[0021] Among them, catalyst I and catalyst II are catalysts, the positive electrode 2-2 and the negative electrode are electrodes, and it is a proton membrane. The proton exchange membrane is an ion conduction membrane that selectively permeates protons (H+). It allows protons to move from the anode to the cathode, but does not allow electrons to pass directly, thus forcing electrons to flow through the external circuit to generate current. When water is injected into the oxygen generator from the water injection end, the external current is respectively loaded onto the negative electrodes and positive electrodes of the two motors through the positive electrode power connection port II and the negative electrode power connection port II. When the current passes through the electrolytic cell, an oxidation reaction occurs at the anode, and water molecules (H2O) lose electrons (e-) to generate oxygen (O2) and protons (H+). The protons migrate to the cathode through the proton exchange membrane. At the cathode, the protons and electrons combine to undergo a reduction reaction to generate hydrogen (H2);

[0022] In this way, the process of electrolyzing water to generate oxygen and hydrogen is completed. The back-to-back design of the electrolytic water device and the hydrogen fuel cell means that theoretically no energy and water are consumed during the system operation. During actual operation, the consumption of energy and water becomes only to compensate for the losses brought about by the non-ideality of the two mutually reverse reaction processes, and the operation cost is greatly reduced. Hydrogen does not need to be stored during the whole production process, which is safe; no waste is generated during the production process, which is environmentally friendly. The generated oxygen has a high purity and less water resources are consumed. Description of the Drawings

On the proton exchange membrane electrolytic water oxygen generator 1-4, a positive electrode power connection port 1-8 and a negative electrode power connection port 1-7 are installed. An external power supply 1-9 is installed on the negative electrode power connection port 1-12, and an external power supply three 1-11 is installed on the positive electrode power connection port 1-10. An external power supply one 1-13 is connected to the positive electrode power connection port 1-8. The external power supply three 1-11 and the external power supply one 1-13 are connected in parallel with each other. An external power supply two 1-14 is connected to the negative electrode power connection port 1-7. The negative electrode power connection port 1-12 and the external power supply two 1-14 are connected in parallel.

[0032] The catalytic coating structure includes a catalyst one 2-1, a positive electrode 2-2, a negative electrode 2-3, and a catalyst two 2-4;

[0033] A proton membrane 2-7 is covered between the proton exchange membrane electrolytic water oxygen generators 1-4. The positive electrode 2-2 and the negative electrode 2-3 are respectively covered on both sides of the proton membrane 2-7. The catalyst one 2-1 is filled outside the positive electrode 2-2, and the catalyst two 2-4 is filled outside the negative electrode 2-3.

[0034] The positive and negative electrode structure includes a positive electrode power connection port two 2-6 and a negative electrode power connection port two 2-5. The positive electrode power connection port two 2-6 and the negative electrode power connection port two 2-5 are respectively installed on one side of the proton exchange membrane electrolytic water oxygen generator 1-4.

A water injection end 2-8 is installed outside the proton exchange membrane electrolytic water oxygen generator 1-4.

[0038] Such as Figure 1 And Figure 2As shown in the figure, the working process of an oxygen generation device provided in this embodiment is as follows: Water is added to the proton exchange membrane electrolytic water oxygen generator 1-4 through the water injection port 1-6. External power drives the proton exchange membrane electrolytic water oxygen generator 1-4 to electrolyze water through the proton exchange membrane electrolytic water oxygen generator 1-14 and the external power supply 1-13 to generate oxygen and hydrogen respectively. Among them, oxygen is output through the oxygen channel 1-5 for standby. The generated hydrogen is supplied to the hydrogen fuel cell 1-2 through the pipeline 1-3 for power generation. The hydrogen fuel cell 1-2 generates power by mixing the air entering through the channel 1-1 and the hydrogen entering through the pipeline 1-3. The generated power is used by the proton exchange membrane electrolytic water oxygen generator 1-4 through the external power supply 3-11 and the negative electrode power connection port 1-12, thus greatly reducing the power consumption. At the same time, the by-product - water generated during the power generation process of the hydrogen fuel cell 1-2 returns to the proton exchange membrane electrolytic water oxygen generator 1-4 through the pipeline 2-15. The proton exchange membrane is an ion conduction membrane that selectively permeates protons (H+). It allows protons to move from the anode to the cathode, but does not allow electrons to pass directly, thereby forcing electrons to flow through the external circuit to generate current. When water is injected into the oxygen generator from the water injection end 2-8, the external current is respectively loaded onto the two motor negative electrodes 2-3 and the positive electrode 2-2 through the positive electrode power connection port 2-6 and the negative electrode power connection port 2-5. When the current passes through the electrolytic cell, an oxidation reaction occurs at the anode, and water molecules (H2O) lose electrons (e-) to generate oxygen (O2) and protons (H+). The protons migrate to the cathode through the proton exchange membrane. At the cathode, the protons and electrons combine to undergo a reduction reaction to generate hydrogen (H2).

[0039] Embodiment 1; As Figure 1 shown in the figure, the hydrogen fuel cell 1-2 and the proton exchange membrane electrolytic water oxygen generator 1-4 are connected together through the pipeline 1-3. Water is added to the proton exchange membrane electrolytic water oxygen generator 1-4 through the water injection port 1-6. External power drives the proton exchange membrane electrolytic water oxygen generator 1-4 to electrolyze water through the proton exchange membrane electrolytic water oxygen generator 1-14 and the external power supply 1-13 to generate oxygen and hydrogen respectively. Among them, oxygen is output through the oxygen channel 1-5 for standby. The generated hydrogen is supplied to the hydrogen fuel cell 1-2 through the pipeline 1-3 for power generation. The hydrogen fuel cell 1-2 generates power by mixing the air entering through the channel 1-1 and the hydrogen entering through the pipeline 1-3. The generated power is used by the proton exchange membrane electrolytic water oxygen generator 1-4 through the external power supply 3-11 and the negative electrode power connection port 1-12, thus greatly reducing the power consumption. At the same time, the by-product - water generated during the power generation process of the hydrogen fuel cell 1-2 returns to the proton exchange membrane electrolytic water oxygen generator 1-4 through the pipeline 2-15. In this way, the water consumption is greatly reduced. Theoretically speaking, in the whole reaction process, water is not consumed, which further reduces the cost. The ideal process also does not consume power. The whole reaction process is only a process of displacing oxygen with water and power as the medium;

[0040] In this way, the processes of absolute power consumption and water consumption in the principle generation process are transformed into compensation activities for compensating the non-ideality of the entire system, and the operating costs and maintenance costs are greatly reduced.

[0041] Example 2: As Figure 2 shown, where catalyst 1 (2-1) and catalyst 2 (2-4) are catalysts, the positive electrode (2-2) and the negative electrode (2-3) are electrodes, 2-7 is a proton exchange membrane. The proton exchange membrane is an ion-conducting membrane that selectively permeates protons (H⁺). It allows protons to move from the anode to the cathode, but does not allow electrons to pass directly, thus forcing electrons to flow through the external circuit to generate current. When water is injected into the oxygen generator from the water injection port 2-8, the external current is respectively loaded onto the two motor negative electrodes 2-3 and the positive electrode 2-2 through the positive electrode power connection port 2-6 and the negative electrode power connection port 2-5. When the current passes through the electrolytic cell, an oxidation reaction occurs at the anode, and water molecules (H₂O) lose electrons (e⁻) to generate oxygen (O₂) and protons (H⁺). The protons migrate through the proton exchange membrane to the cathode. At the cathode, the protons and electrons combine to undergo a reduction reaction to generate hydrogen (H₂);

[0042] In this way, the process of electrolyzing water to generate oxygen and hydrogen is completed. With the back-to-back design of the electrolytic water device and the hydrogen fuel cell, theoretically, the system does not consume energy and water during operation. During actual operation, the consumption of energy and water becomes only the loss caused by compensating for the non-ideality of the two reciprocal reaction processes, and the operating cost is greatly reduced. Hydrogen does not need to be stored during the entire production process, which is safe; no waste is generated during the production process, which is environmentally friendly. The generated oxygen has high purity and less water consumption.

Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
