Detailed Implementation

[0023] This utility model discloses a hydrogen fuel cell filter. The following description, in conjunction with a preferred embodiment (Example 1), is shown in the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.

[0024] See attached diagram. Figures 1 to 8 , Figures 1 to 4 The hydrogen fuel cell filter is shown from different perspectives. Figures 5 to 8 The partial structure of the hydrogen fuel cell filter is shown from different perspectives.

[0025] Example 1.

[0026] Preferably, the hydrogen fuel cell filter includes an inlet pipe 100, an outlet pipe 200, and a filter canister 300. The inlet pipe 100 and the outlet pipe 200 are respectively disposed at two ends of the filter canister 300 and are integrally formed with the filter canister 300, wherein:

[0027] The filter canister 300 has a canister body 310 and an inlet side baffle 320 and an outlet side baffle 330 integrally formed with the canister body 310. The filter canister cavity 301 is located between the inlet side baffle 320 and the outlet side baffle 330 (in other words, the filter canister cavity 301 is formed by the canister body 310, the inlet side baffle 320 and the outlet side baffle 330 surrounding it inward). The filter canister cavity 301 contains (fills) a filter medium (not shown in the figure). The filter medium is in close contact with the inner surface of the canister body 310, the inlet side baffle 320 and the outlet side baffle 330, so that gas that may contain gaseous pollutants is introduced into the filter medium through the inlet pipe 100, and the gas is fully filtered by the filter medium before being output from the outlet pipe 200.

[0028] The air intake side baffle 320 has multiple air intake side through holes 321, each air intake side through hole 321 is connected to the air intake side guide pipe 322, the air intake side guide pipe 322 is located on the side of the air intake side baffle 320 facing the inner cavity 301 of the filter can and is detachably connected to the air intake side baffle 320.

[0029] The air outlet side baffle 330 has multiple air outlet side through holes 331, each air outlet side through hole 331 is connected to the air outlet side guide pipe 332, and the air outlet side guide pipe 442 is located on the side of the air outlet side baffle 330 facing the filter inner cavity 301 and is detachably connected to the air outlet side baffle 330.

[0030] This allows each inlet-side air guide pipe 322 and each outlet-side air guide pipe 332 to be embedded within the filter medium, thereby further increasing the contact area of ​​the filter medium and improving the filtration effect of the filter medium on gaseous pollutants.

[0031] The tank body 310 is provided with a tank body air inlet 311, and the filter tank air inlet space 302 is located between the tank body air inlet 311 and the air inlet side partition 320. The air inlet side through hole 321 and the air inlet pipe 100 are respectively connected to the filter tank air inlet space 302; so that the filter tank air inlet space 302 serves as a buffer area, where gases that may contain gaseous pollutants are temporarily stored in the filter tank air inlet space 302 before being introduced into the filter medium.

[0032] The tank body 310 is provided with a tank body vent 312, and the filter tank vent space 303 is located between the tank body vent 312 and the vent side partition 330. The vent side through hole 331 and the vent pipe 200 are respectively connected to the filter tank vent space 303. This allows the filter tank vent space 303 to serve as a buffer area, where the gas that has been fully filtered by the filter medium is temporarily stored in the filter tank vent space 303 and then output through the vent pipe 200.

[0033] The hydrogen fuel cell filter also includes a sampling tube 400, which extends through and is fixedly connected to the tank 310. The sampling tube 400 is located between the inlet side baffle 320 and the outlet side baffle 330, and is close to the outlet side baffle 330. This allows gas sampling to be performed through the sampling tube 400 when it is necessary to determine whether the concentration of gaseous pollutants in the filter tank cavity 301 exceeds the standard.

[0034] The hydrogen fuel cell filter also includes a positioning bracket 340, which is fixedly connected to the tank 310. The positioning bracket 340 has multiple positioning holes 341 so that the positioning bracket 340 can be further connected to other structures of the hydrogen fuel cell device.

[0035] It is worth mentioning that the specific components and other technical features of the filter medium involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0036] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
