Abstract

The invention provides an air compressor for a fuel cell, which is applied to the technical field of the fuel cells. A driving gear (2) in a rotor casing (1) of the air compressor for the fuel cell is connected with a driving shaft (4); a driven gear (3) is connected with a driven shaft (5); the driving shaft (4) is connected with an input shaft (6); a driving rotor (7) is arranged on the driving shaft (4); a driven rotor (8) is arranged on the driven shaft (5); an air inlet (9) in the rotor casing (1) is close to the driving rotor (7) and the driven rotor (8) in position; the input shaft (6) is connected with a motor (10). According to the air compressor for the fuel cell, provided by the invention, the durability and the reliability of the air compressor for the fuel cell are effectively improved, further the overall performance of an air supply system is improved, the volumetric efficiency and the insulating efficiency of the air compressor are improved, and NVH (Noise Vibration and Harshness) performance of the air compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of fuel cells for new energy automobile parts, and more specifically relates to an air compressor for fuel cells. Background technique [0002] A fuel cell is a device that converts the chemical energy of hydrogen and oxygen into electrical energy through an electrode reaction. The biggest feature of this device is that the reaction process does not involve combustion, and the energy conversion efficiency is not limited by the Carnot cycle. Its energy conversion efficiency is as high as 60%. -80%. In a fuel cell, hydrogen and oxygen react electrochemically at the anode and cathode respectively to generate current. The oxygen in it can be obtained directly from pure oxygen or air, and it is more convenient and economical to use air. In order to obtain higher power density and better performance, automotive fuel cells must work at higher pressures, especially for the cathode reactants (oxygen or air). The pe...
