Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen fuel cells, and in particular relates to a highly integrated hydrogen fuel cell device. Background Art

[0002] The working principle of a hydrogen fuel cell is to supply hydrogen and oxygen to the anode and cathode of the battery respectively, and an electrochemical reaction occurs under the action of a catalyst to generate electricity and water vapor. However, at present, water vapor from hydrogen fuel cells is usually discharged directly. Water vapor contains potential water resources. If it is discharged directly without being utilized, this part of the water resources will be wasted. In some areas, the acquisition and supply of water resources may be limited. Therefore, failure to recycle the water in the water vapor is a waste of resources. Direct discharge of water vapor may have a certain impact on the environment. A large amount of water vapor discharged into the atmosphere may cause an increase in local humidity, which may cause fog or precipitation, and affect meteorological conditions and ecosystems. In order to solve this problem, we have developed a highly integrated hydrogen fuel cell device. Utility Model Content

[0024] The water vapor recovery assembly 500 includes an air supply pipe 501, an air pump 502 and a branch pipe 504. The left sides of the three exhaust valves 170 are respectively connected to an air pump 502 through the air supply pipe 501. The left ends of the three air pumps 502 are respectively installed with a connecting pipe 503. The left ends of the three connecting pipes 503 are connected to a branch pipe 504. The left side of the branch pipe 504 is connected to an air intake pipe 505. The left side of the air intake pipe 505 is connected to an air intake pipe 507 through an air intake pipe 506. An exhaust fan 508 is respectively installed in the middle of the air intake pipe 506 and in the middle of the three air pumps 502.

[0025] A water vapor treatment box 600 is arranged on the left side of the air inlet pipe 507, a condenser 120 is installed on the upper part of the water vapor treatment box 600, a drain valve 130 is installed on the lower left side of the condenser 120, an activated carbon water filter plate 150 is arranged below the drain valve 130, a water storage chamber 900 is opened at the lower part of the water vapor treatment box 600, and an ultraviolet sterilization lamp 110 is installed on the left and right sides of the water storage chamber 900 respectively.

[0026] Three hydrogen intake valves 200 are installed at the lower right side of the integrated outer box 100, and a protective gas intake valve 300 is installed under each of the three hydrogen intake valves 200. The three hydrogen intake valves 200, the three protective gas intake valves 300 and the three exhaust valves 170 are respectively connected to three groups of hydrogen fuel cells.

[0027] A heat dissipation upper frame 400 is installed on the upper right side of the integrated outer box 100. The heat dissipation upper frame 400 is connected to the inside of the integrated outer box 100. A heat dissipation fan is installed inside the heat dissipation upper frame 400. The heat generated by the three groups of hydrogen fuel cells in the integrated outer box 100 can be discharged to the outside through the heat dissipation fan.

[0028] For example, see Figure 1Since three groups of hydrogen fuel cells are integrated in the integrated outer box 100, hydrogen and protective gas can enter the three groups of hydrogen fuel cells through the hydrogen inlet valve 200 and the protective gas inlet valve 300 respectively, which makes the hydrogen fuel cell have the advantage of high integration. This integrated design can reduce the volume and weight of the system and improve the overall compactness and portability. By integrating multiple hydrogen fuel cell units together, the energy density and output power of the system can be improved to meet higher energy needs. In addition, the design of the three groups of batteries also provides a certain redundant backup capability. If one group of batteries fails or its performance degrades, the other two groups of batteries can still continue to work, ensuring the reliability and continuity of the system.

[0029] The air inlet pipe 507 is connected to the air inlet valve of the condenser 120. The top of the condenser 120 is fixed to the inside of the water vapor treatment box 600, and the left and right sides below are connected to the inside of the water vapor treatment box 600 through fixing plates.

[0030] The left side of the activated carbon water filter plate 150 is connected to the inside of the water vapor treatment box 600 through the left fixing plate 140 , and the right side thereof is connected to the condenser 120 through the right fixing plate 160 .

[0031] A water outlet valve is installed at the lower back of the water vapor treatment box 600, and multiple groups of ventilation and heat dissipation holes 700 are respectively opened at the upper front and back of the water vapor treatment box.

[0032] A water level observation plate 800 is installed in the middle of the lower front side of the water vapor treatment box 600. The water level observation plate 800 is made of organic glass.

[0033] For example 2, please refer to Figures 1 to 4 , the water vapor generated by the three groups of hydrogen fuel cells can enter the gas pipeline 501 through the three exhaust valves 170 respectively, and the air inlet cylinder 506 and the exhaust fans 508 inside the three exhaust cylinders 502 can be started in advance. The exhaust fans 508 inside the three exhaust cylinders 502 can respectively exhaust the water vapor inside the gas pipeline 501 and transmit it to the inside of the branch pipe 504 through the connecting pipe 503. Under the action of the exhaust fan 508 inside the air inlet cylinder 506, the water vapor inside the branch pipe 504 can enter the air inlet pipe 505, and then the water vapor can enter the condenser 120 through the air inlet pipe 507 under the action of the exhaust fan 508 inside the air inlet cylinder 506. When the water vapor enters the condenser 120, the temperature inside the condenser 120 is lower than the saturation temperature of the water vapor, and the water vapor will condense into small water droplets in the condenser 120. These small water droplets will gather together to form liquid water, and finally be discharged to the activated carbon water filter plate 150 through the drain valve 130;

[0034] Since some liquid water may be mixed with impurities, the activated carbon water filter plate 150 can filter the impurities mixed in the liquid water to make the liquid water purer. The filtered liquid water can enter the water storage chamber 900 for storage, and then the two ultraviolet sterilization lamps 110 can be powered on and lit, so that the ultraviolet sterilization lamps 110 can emit ultraviolet light to sterilize and disinfect the liquid water, so that the liquid water can be easily reused. The recovered liquid water can be discharged to the outside through the water outlet valve. Through the above steps, the final effect is that the water vapor generated by the hydrogen fuel cell can be collected, cooled and converted into liquid water through the condenser 120, and then the recovered liquid water is filtered through the activated carbon water filter plate 150 to remove impurities and pollutants therein and improve the quality of the water. The filtered water can enter the water storage chamber 900 for storage, and the water body is sterilized and disinfected by the ultraviolet sterilization lamp 110 to ensure the safety of water quality, so that the water vapor generated by the hydrogen fuel cell can be easily recovered and reused.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
