Fuel Cell Powertrain Air Filters

Abstract

The invention discloses an air filter for a fuel cell power system, comprising an air filter pipeline, one end of the air filter pipeline is provided with an air inlet, and the other end is provided with an air compressor connection port; the air filter pipeline is provided with a filtering structure, The filter structure includes a plurality of gas adsorption layers and a gas concentration sensor corresponding to each gas adsorption layer, and the plurality of gas adsorption layers are arranged in sequence from the air inlet to the air compressor connection port; the gas adsorption layer and the corresponding The gas concentration sensor corresponds to the same gas, and the gas concentration sensor is arranged on the side of the corresponding gas adsorption layer close to the connection port of the air compressor. The air filter pipeline is tubular, flexible in layout, does not occupy the overall space of the front cabin, and effectively saves the layout space of the front cabin; behind each gas adsorption layer is a gas concentration sensor for monitoring the corresponding gas concentration, so as to replace the relevant gas adsorption in time Layered filter element to ensure the filtering effect.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to an air filter for a fuel cell power system. Background technique [0002] At present, common fuel cell vehicles use air as the oxidant, however, dust, impurity particles, harmful gases (such as H 2 S, SO 2 , CO, NOX, NH 3 , toluene, n-butane, etc.) will affect the performance of the fuel cell and reduce the service life of the fuel cell. In order to eliminate the impact of impurity particles and harmful gases in the air on the fuel cell, an effective method is to add an air filter with a function similar to that of a traditional fuel vehicle. The difference is that the air filter used in the fuel cell power system not only filters out particles, but also absorbs harmful gases. [0003] Recently, air filters for fuel cell power systems used in passenger cars either adopt an air filter structure similar to that of traditional fuel oil. Although they have physical filtration and chemi...
