The wind blown in by the blowing device 3 passes through the fuel cell monomer 2 and the gas processing device 4 in sequence during the process of being blown out from the blowing port and moving upward, driving the hydrogen and toxic gas generated by the reaction of the fuel cell monomer 2 to the upper side. After the toxic gas is treated by the toxic gas device and the hydrogen is treated by the hydrogen removal device, the remaining other safety gases are discharged through the first air outlet 14, preventing explosion caused by hydrogen in the shell 1 and protecting the environment at the same time.

[0033] In this embodiment, the poisonous gas treatment device is installed below the hydrogen elimination device, the mixed gas first flows through the poisonous gas treatment device and then flows through the hydrogen elimination device, the gas outlet of the poisonous gas treatment device is connected to the gas inlet of the hydrogen elimination device through a pipeline, a one-way valve is arranged on the pipeline, the mixed gas preferentially passes through the poisonous gas treatment device to treat the poisonous gas, the mixed gas with the poisonous gas removed flows through the pipeline and the one-way valve to the hydrogen elimination device, the hydrogen is removed, and then discharged through the first gas outlet. The one-way valve is arranged to prevent the mixed gas from flowing back to the poisonous gas treatment device and mixing with the poisonous gas again.

[0034] like Figure 2 As shown, a bottom bracket 21 is fixed to the bottom of the fuel cell unit 2, and a top bracket 22 is fixed to the top of the fuel cell unit 2. The bottom bracket 21 and the top bracket 22 are both fixed in the shell 1. The shell 1 can be an integrally formed closed structure or a detachable structure. Figure 1 As shown, the housing 1 includes an upper housing 11, a lower housing 12 and an intermediate housing 13. The upper housing 11 and the lower housing 12 are detachably connected to the intermediate housing 13, respectively. The bottom bracket 21 is fixed in the lower housing 12, the fuel cell unit 2 and the top bracket 22 are fixed in the intermediate housing 13, and the gas processing device 4 is fixed in the upper housing 11. The housing 1 is set to be detachable for easy disassembly and maintenance. The setting of the bottom bracket 21 and the top bracket 22 facilitates the heat dissipation of the fuel cell unit 2 and provides a larger air flow space.

[0035] like Figure 4 As shown, the air outlet includes a first air outlet 51 and a second air outlet 52. The first air outlet 51 and the second air outlet 52 are vertically upward or inclined upward, and the angle of inclination is preferably less than or equal to 60° with the vertical direction. The direction of the first air outlet 51 and the second air outlet 52 is set to control the angle of the air outlet so that the wind flows from bottom to top to dissipate heat to the fuel cell group. The first air outlet 51 is located below the fuel cell monomer 2 and is arranged in the bottom bracket 21. The second air outlet 52 is located between adjacent fuel cell monomers 2, that is, between adjacent bottom brackets 21. In this embodiment, the first air outlet 51 is a round hole, and the second air outlet 52 is a nozzle-type hole, similar to a shower nozzle structure, and the second air outlet 52 blows out divergent wind. The wind blown out of the first air outlet 51 preferentially dissipates heat from the bottom of the fuel cell monomer 2, and the divergent wind blown out of the second air outlet 52 dissipates heat from the side of the fuel cell monomer 2, and the second air outlet 52 accelerates the air flow between adjacent fuel cell monomers 2 to accelerate heat dissipation.

[0036] There are multiple air ducts 5, and the multiple air ducts 5 are arranged along the length direction of the fuel cell monomer 2. Therefore, each row of first air blowing ports 51 and each row of second air blowing ports 52 are arranged along the length direction of the fuel cell monomer 2, and a row of first air blowing ports 51 is provided below each fuel cell monomer 2, and a row of second air blowing ports 52 is provided between adjacent fuel cell monomers 2.

[0037] A horizontally arranged second air outlet 23 is provided on the bottom bracket 21, and the axial direction of the second air outlet 23 is perpendicular to the length direction of the fuel cell monomer 2. The second air outlet 23 supplements the direction that the first air outlet 51 and the second air outlet 52 cannot reach. A horizontally arranged first air inlet 24 and a third air outlet 25 are provided on the top bracket 22, and the axial direction of the first air inlet 24 is perpendicular to the length direction of the fuel cell monomer 2, and the axial direction of the third air outlet 25 is parallel to the length direction of the fuel cell monomer 2. The upward wind energy through the first air outlet 51, the second air outlet 52 and the second air outlet 23 enters the first air inlet 24, flows through the top of the fuel cell monomer 2 to dissipate heat, and then flows out from the third air outlet 25. The first air outlet 51, the second air outlet 52, the second air outlet 23, the first air inlet 24 and the third air outlet 25 plan the flow path of the wind in the shell 1, and the fuel cell monomer 2 is dissipated in all directions at 360 degrees. The direction of wind flow is as follows: Figure 3-5 As indicated by the arrow.

[0038] A second air inlet 15 is provided on the wall of the shell 1 corresponding to the gas processing device 4, that is, the second air inlet 15 is arranged on the wall of the upper shell 11, and the second air inlet 15 is connected with the third air outlet 25 through a pipeline. The wind flowing out of the third air outlet 25 contains mixed gases such as hydrogen and toxic gases, which enter the upper shell 11 through the second air inlet 15 and flow through the gas processing device 4. After the toxic gas processing device of the gas processing device 4 removes the toxic gas in the mixed gas and the hydrogen removal device removes the hydrogen in the mixed gas, the other gases are discharged from the shell 1 through the first air outlet 14, so as to dissipate heat in time and prevent the explosion caused by excessive hydrogen stored in the shell 1. The other gases discharged are safe gases to protect the environment.

[0039] The fuel cell group is electrically connected to the air blower 3. When working, the fuel cell group provides power to the air blower 3, and no additional power is required. The structure is simple and easy to carry. In order to reduce the overall area of ​​the integrated fuel cell, the air blower 3 is fixed to the bottom of the shell 1, and the legs 6 are fixed at the four corners of the bottom of the shell 1 to play a supporting role.

[0040] When the fuel cell starts to work, the blower 3 starts to work, and the blower 3 conveys external wind to the first blowing port 51 and the second blowing port 52. The gas reaches the bottom of the fuel cell unit 2 through the first blowing port 51 for heat dissipation. The second blowing port 52 is a nozzle-type hole, blowing air upward. The second air outlet 23 has a horizontal outlet to supplement the direction that the first blowing port 51 cannot blow. The gas flows through the fuel cell unit 2 to take away the heat and the mixed gas such as hydrogen generated by the reaction and a small amount of toxic gas, and flows into the first air inlet 24 to take away the heat from the top of the fuel cell unit 2, and enters the gas processing device 4 through the third air outlet 25 and the second air inlet 15. After removing the toxic gas and hydrogen, it is discharged through the first air outlet 14.

[0041] The present invention realizes 360° all-round heat dissipation of the fuel cell monomer, has good heat dissipation effect, improves the working efficiency and service life of the fuel cell, removes poison gas and hydrogen before discharging, avoids explosion caused by hydrogen stored in the shell, and protects the environment at the same time.
