Air filter and fuel cell vehicle

Abstract

The invention discloses an air filter and a fuel cell vehicle, which belong to the technical field of new energy vehicles. The air filter comprises: an electrostatic adsorption device arranged in a casing, and the electrostatic adsorption device is configured to absorb and capture air Particles in the particulate matter; the electric heating catalyst filter layer is arranged in the housing and is located downstream of the electrostatic adsorption device. The electric heating catalyst filter layer is configured to be repeatedly heated to the regeneration temperature at intervals of a preset time, and the catalyst in the electric heating catalyst filter layer Can react with oxidizing compounds in the air. Compared with the existing technology, the air filter does not need to use consumables such as air filter elements, which saves costs, and the air inlet resistance is small, which reduces the parasitic power consumption of the air compressor; the electric heating catalyst filter layer can be reused, compared with Due to the existing technology, there is no need to use consumables, no need to replace the filter element regularly, and the catalytic purification effect can be maintained for a long time, reducing the cost of the user's car.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an air filter and a fuel cell vehicle. Background technique [0002] With the continuous improvement of people's living standards, cars have become an essential tool for people to travel. With the increasingly serious urban smog, fuel cell vehicles have become the most mainstream development and use direction in the automotive field. Its multiple advantages such as fast filling, zero emissions, and low temperature resistance have attracted more and more attention from the industry and consumers. [0003] Compared with traditional internal combustion locomotives, hydrogen fuel cell vehicles mainly rely on the reaction between the outside air and the hydrogen stored on the vehicle to generate electricity to drive the vehicle. In this process, due to the characteristics of the catalyst and proton exchange membrane in the fuel cell, it is generally necessary to purify an...

AI Technical Summary

Problems solved by technology

[0006] 1. In order to fully react with the air, the chemical filter element with the function of removing harmful gases greatly increases the resistance of the air inlet and increases the parasitic power consumption of the air compressor;

[0007] 2. The cost of the chemical filter element is high, and the filter element needs to be replaced regularly, which increases the user's vehicle cost;

[0008] 3. The filter material in the chemical filter element has been chemically treated, and long-term storage will reduce the purification effect
