Detailed Description

The present invention will be more clearly and completely described below with reference to the accompanying drawings.

Fig. 1-3 show a hydrogen fuel cell automotive air filter, comprising: upper housing 100, lower housing 200, air filter 300, and chemisorption filter 400. The upper casing 100 has an air outlet cavity (not shown), and the upper casing 100 has an air outlet 110 connected to the air outlet cavity. The lower housing 200 has an air inlet cavity (not shown), the lower housing 200 has an air inlet 210 connected to the air inlet cavity, and the upper housing 100 covers the lower housing 200. The air filter 300 is fixed in the lower case 200 and separates the air outlet cavity and the air inlet cavity. The chemisorption filter element 400 is fixed in the upper case 100, and the maximum adsorption surface of the chemisorption filter element 400 is opposite to the air filter element 300.

Air is sucked into the air inlet cavity from the air inlet 210 of the lower housing 200, then particulate impurities, water vapor and the like in the air are filtered by the air filter element 300, then the air enters the air outlet cavity to contact with the chemical adsorption filter element 400, and finally the air is discharged through the air outlet 110. The chemical adsorption filter element 400 can adsorb nitrogen oxides, sulfides, acidic substances and the like in the gas, so that the gas is further purified, and the corrosion of the gas filtered by the air filter element 300 to a proton exchange membrane in a hydrogen fuel cell automobile is reduced. The biggest adsorption surface of chemisorption filter core 400 in this scheme just can make the gaseous direct flow direction chemisorption filter core 400 of after filtering to air filter core 300, increases chemisorption's efficiency, reinforcing chemisorption's effect.

The fixing member is fixed to the upper case 100, the chemical adsorption cotton 410 is fixed in the fixing member, and a plurality of through mesh holes 425 are formed on the outer circumferential surface of the fixing member. The chemisorption cotton 410 mainly functions to adsorb nitrogen oxides, sulfides and acidic substances in the gas. The use of the mesh openings 425 in the mounting assembly ensures that the chemisorbed cotton 410 is secured within the mounting assembly without preventing gas from contacting the chemisorbed cotton 410. In order to place the chemical adsorption cotton 410 in the fixing component, the fixing component includes a cover plate 421 and a receiving part 422, the receiving part 422 has a receiving groove, the chemical adsorption cotton is located in the receiving groove, and the cover plate 421 covers the opening of the receiving groove.
