All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.

The practical principle of the compressor of the invention is as follows:
the chemical reaction of the fuel cell has strict requirements on parameters such as temperature, humidity, pressure and flow of air, and the common industrial compressor cannot meet the working requirements of the fuel cell. Therefore, a compressor having superior performance and a good matching with the fuel cell system is very important for the fuel cell system. The basic requirements of the air compressor special for the fuel cell engine are oil-free, high efficiency, miniaturization, low cost, low noise, small flow area of a surge line, good dynamic response capability and the like.
A turbine compressor belongs to a centrifugal compressor. The principle of pressurization is that energy is transferred to air through a high-speed impeller to enable the gas to obtain a very high speed, and then a diffuser pipe is used for reducing the flow rate of the gas and increasing the pressure of the gas. The efficiency of the compressor can reach more than 75%, and meanwhile, the compressor can provide equivalent flow rate in a small volume under the support of a high-speed motor.
When the air passes through the first turbine, the air is pressurized for the first time under the driving of the high-speed motor, flows to the second turbine through the outside of the air compressor, and is pressurized for the second time, and the process of gas pressurization is totally performed twice. Meanwhile, the motor shaft is a hollow shaft, so that the rotating speed of the motor can be effectively increased and the vibration can be reduced compared with a solid motor shaft.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
