Description

Technical Field

[0001] This utility model relates to the field of hydrogen fuel cell vehicle technology, specifically a hydrogen fuel cell vehicle with a buoyancy device. Background Technology

[0002] Hydrogen fuel cells used in hydrogen-powered vehicles such as hydrogen-powered bicycles, hydrogen-powered drones, hydrogen-powered forklifts, hydrogen-powered ships, and hydrogen-powered cars are mainly classified into two types based on their humidification and heat exchange system technologies: air-cooled and liquid-cooled. Air-cooled fuel cells primarily use fans to pressurize the gas, rapidly removing the reaction heat center from the fuel cell. The air pressure is used to regulate the reaction temperature and humidity within the fuel cell. However, it is clearly impossible to precisely control both humidity and temperature using only the fan pressure. For the membrane electrode assembly (MEA) to achieve its optimal efficiency, it must be kept in an environment with constant optimal reaction temperature and humidity. Excessive humidity can lead to flooding, while insufficient humidity or complete drying can increase internal resistance, causing the fuel cell to burn out and cease operation.

[0003] However, existing air-cooled hydrogen-powered bicycles cannot travel on flooded roads and may become trapped, posing a danger. Therefore, there is a need for a hydrogen-powered vehicle with a buoyancy device. Utility Model Content

[0035] The hydrogen fuel cell includes a housing 19, an inlet 20, an outlet 21, a siphon damper 22, a hydrogen storage tank 23, a humidifying filter membrane, a fuel cell stack 24, a hot air fan 25, and a DC-DC hydrogen-electric dual-function controller 26. The housing 19 is installed inside the vehicle body 1 and is fixedly connected to the cavity sidewall of the vehicle body 1 by bolts or other means. The inlet 20 and outlet 21 are located on the housing 19, with the inlet 20 located on the bottom wall of the housing 19 and the outlet 21 located on the side wall of the housing 19. The siphon damper 22 is installed inside the housing 19. 2. The siphon damper 22 is fixedly connected to the inner wall of the housing 19 by means of adhesive or other methods. The siphon damper 22 is a high-resilience open-pore sponge. The hydrogen storage bottle 23 is set on the siphon damper 22 and is fixedly connected to the housing 19 by means of brackets, bolts, etc. The hydrogen storage bottle 23 is placed in the groove opened on the siphon damper 22. The hydrogen storage bottle 23 is used to supply hydrogen to the fuel cell stack 24 for power generation. The humidifying filter membrane includes an air-permeable layer 39 and an air-permeable layer 40, and a hydrophilic humidifying layer 41 set between the air-permeable layer 39 and the air-permeable layer 40. The humidifying filter membrane is fixed to the fuel cell stack 24 by bolts. 4. The ventilation layer 39 is attached to the air inlet at the bottom of the fuel cell stack 24, and the permeable layer 40 is attached to the air inlet 20 on the shell 19. The ventilation layer 39 and the permeable layer 40 sandwich the hydrophilic humidifying layer 41 in between. Several hydrophilic humidifying layers 41 are spaced apart between the ventilation layer 39 and the permeable layer 40, and their ends are connected and inserted into the siphon damper 22. This facilitates the hydrophilic humidifying layer 41 to absorb water from the siphon damper 22. The spaced hydrophilic humidifying layers 41 prevent water from clogging the mesh on the ventilation layer 39 and the permeable layer 40, thus not affecting the air intake and hydrophilic humidification. Layer 41 can be selected according to the actual use of the appropriate water-absorbing film. The fuel cell stack 24 is set at the air inlet 20 and above the humidifying filter membrane. The fuel cell stack 24 is fixedly connected to the housing 19 by means of bolts, etc. The hot fan 25 is set on the fuel cell stack 24 and is fixedly connected to the fuel cell stack 24 by means of bolts, etc. The hot fan 25 is set at the air outlet of the fuel cell stack 24. The DC-DC hydrogen-electric dual controller 26 is set on the housing 19 and is fixedly connected to the housing 19 by means of screws, etc.

[0036] The hot air fan 25 blows the hot air generated by the fuel cell stack 24 toward the inclined surface on the casing 19, thereby guiding it to the top of the hydrogen storage tank 23. As the hydrogen storage tank 23 releases hydrogen and cools down, the water vapor in the hot air comes into contact with the hydrogen storage tank 23 and condenses, flowing down the outer wall of the hydrogen storage tank 23. The siphon damper 22 absorbs and stores the condensate flowing down from the top of the hydrogen storage tank 23. The hydrophilic humidification layer 41 absorbs the condensate in the siphon damper 22. When the hot air fan 25 draws air from the fuel cell stack 24, the air passes through the ventilation layer 39 and the permeable layer 40 for filtration, mixes with the moisture on the hydrophilic humidification layer 41, and is blown toward the top of the hydrogen storage tank 23 after the fuel cell stack 24 absorbs heat, thus forming a water circulation. The gas enters from the air inlet 20 and exits from the air outlet 21.

[0037] An air intake hood 27 is provided at the air intake 20, and an air outlet hood 28 is provided at the air outlet 21. The air intake hood 27 is provided on the housing 19 and located at the air intake 20. The air intake hood 27 is fixedly connected to the housing 19 by means of bolts or the like.

The air intake pipe 2 includes an air intake horizontal section 201 provided on the air intake hood 27, an air intake upward section 202 connected to the air intake horizontal section 201, and an air intake bending section 203 provided on the air intake upward section 202 and extending out of the vehicle body 1. By providing the air intake upward section 202, the height of the air intake end of the air intake pipe 2 is increased, preventing water from entering the air intake 20 when wading through water. By providing the air intake horizontal section 201, the design of the air intake horizontal section 201 is avoided, reducing the direct inflow of water into the housing 19 in the event of accidental water ingress.

[0038] A vent hood 28 is mounted on the housing 19 and located at the vent 21. The vent hood 28 is fixedly connected to the housing 19 by means of bolts or the like. A vent pipe 3 is mounted on the vent hood 28 and is fixedly connected to the vent hood 28 by means of bolts or the like. The vent pipe 3 includes a recessed section 301 mounted on the vent hood 28, a horizontal vent section 302 mounted on the recessed section 301, an upward vent section 303 mounted on the horizontal vent section 302, and a bent vent section 304 mounted on the upward vent section 303 and extending out of the vehicle body 1. The upward vent section 303 increases the height of the vent end of the vent pipe 3, preventing water from entering the vent 21 when the pipe is submerged. The horizontal vent section 302 prevents water from entering the housing 19 directly in case of accidental water ingress.

[0039] A booster fan 29 is installed on the intake rising section 202 and the exhaust rising section 303. The booster fan 29 is fixedly connected to the intake rising section 202 and the exhaust rising section 303 respectively by welding or other means to improve the efficiency of intake or exhaust. A drain pipe 30 is installed on the intake horizontal section 201 and the exhaust horizontal section 302 respectively by welding or other means. A drain cover 31 is installed on the drain pipe 30. The drain cover 31 extends out of the vehicle body 1 and is threadedly connected to the drain pipe 30. Unscrewing the drain cover 31 can discharge any dirt that accidentally enters the intake horizontal section 201 or the exhaust horizontal section 302.

[0040] The hydrogen fuel cell vehicle also includes an extension hose, which is used for temporary connection when the vehicle body 1 is wading through deep water. The extension hose includes an intake extension pipe 32 inserted into the intake pipe 2 and an exhaust extension pipe 33 inserted into the exhaust pipe 3. Both the intake extension pipe 32 and the exhaust extension pipe 33 can be made into flexible hoses for easy storage when not in use. A breathing tube 34 is provided on the intake extension pipe 32, and the breathing tube 34 is integrally formed and fixedly connected to the intake extension pipe 32. A breathing mask 35 is provided on the breathing tube 34, and the breathing mask 35 is fixedly connected to the breathing tube 34 by adhesive or other means. The breathing mask 35 is provided with a rubber band for easy wearing by the user, and a mask with good airtightness can be selected. Both the intake extension pipe 32 and the exhaust extension pipe 33 are provided with floats 36, and the floats 36 are fixedly connected to the intake extension pipe 32 or the exhaust extension pipe 33 by ropes or other means. The float 36 is used to make the ends of the air inlet extension pipe 32 and the air outlet extension pipe 33 float on the water surface. Both the air inlet extension pipe 32 and the air outlet extension pipe 33 are provided with a connector 37. The connector 37 is fixedly connected to the air inlet extension pipe 32 or the air outlet extension pipe 33 by means of adhesive or other means. The connector 37 is provided with a second sealing ring 38. The second sealing ring 38 is fitted into the annular groove opened on the connector 37 by means of adhesive or other means. The connector 37 is used to allow the air inlet extension pipe 32 to be detachably inserted into the air inlet bend section 203 and the air outlet extension pipe 33 to be detachably inserted into the air outlet bend section 304. The size of the connector 37 is adapted to the size of the air inlet bend section 203 and the air outlet bend section 304. The second sealing ring 38 can fix the connector 37 in the air inlet bend section 203 or the air outlet bend section 304 and also achieve a sealing effect.

[0041] Working principle: During use, the booster fan 29 on the intake pipe 2 blows gas towards the intake port 20, allowing the gas to enter from the air inlet at the bottom of the fuel cell stack 24. The hot air fan 25 blows the heated air in the fuel cell stack 24 towards the inclined surface on the casing 19, thus guiding it to the top of the hydrogen storage tank 23. As the hydrogen storage tank 23 releases hydrogen and cools down, the water vapor in the hot air condenses upon contact with the hydrogen storage tank 23 and flows down along the outer wall of the hydrogen storage tank 23. The siphon damper 22 absorbs and stores the condensate flowing down from the top of the hydrogen storage tank 23. The hydrophilic humidifying layer 41 absorbs the condensate in the siphon damper 22, allowing the hot air fan 25 to draw gas from the fuel cell stack 24. When the air is filtered through the ventilation layer 39 and the permeable layer 40, it mixes with the moisture on the hydrophilic humidifying layer 41. After the fuel cell stack 24 absorbs heat, the air is blown back to the top of the hydrogen storage tank 23, so that the moisture forms a cycle. The gas is discharged from the outlet 21 and sent into the exhaust hood 28. The booster fan 29 on the exhaust pipe 3 discharges the exhaust gas in the exhaust hood 28 through the exhaust pipe 3. When it is necessary to wade through water, pull the pull bar 9 to move the first airbag 10 and the second airbag 11 out of the vehicle body 1. Insert the plug 17 into the exhaust pipe 3. Connect the inflation head 16 to the inflation nozzle 12 and use the exhaust pipe 3 to inflate the first airbag 10 and the second airbag 11.
