Abstract

The invention discloses an air bearing compressor for a fuel cell. The air bearing compressor is characterized by comprising a rotating motor, a driving motor an impeller shell, wherein an impeller is arranged in the impeller shell; an air bearing which is radially coupled with the driving motor is arranged in the driving motor. According to the air bearing compressor disclosed by the invention, a state control system for controlling the physical quantities of motor speed, temperature, flow and pressure is designed, so that the rotating speed of the motor can be fed back and controlled comprehensively in real time. Through integration of a design thought and the state control system for controlling a plurality of physical quantities, the air bearing compressor for the fuel cell has the characteristics of small size, low cost, simple structure, low energy consumption, long service life and the like, the requirements of a new energy electric vehicle, a high-speed fan and the like on the fuel cell can be met, and the application field and application range of the air bearing compressor are further widened.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an air bearing compressor for fuel cells. Background technique [0002] Under the pressure of energy and environmental protection, new energy vehicles will undoubtedly become the development direction of future automobiles. Hydrogen fuel cell has become a veritable green fuel in fuel cell vehicles because of its pollution-free, noise-free and high efficiency. It is particularly important to provide clean compressed air to hydrogen fuel cells, so the compressor plays an important role in the battery stack. It is a key technology in fuel cells, which must meet the requirements of no oil, small size, high voltage, low noise, low power consumption and long life. [0003] Conventional compressors use mechanical contact rolling bearings to support the main shaft. The higher the speed, the higher the requirements for bearing precision and lubrication, and the shorter the service li...
