The technical scheme of the compressor of the existing fuel cell mainly comprises a turbine type compressor, a screw compressor and a centrifugal compressor. Wherein the mass and noise can be relatively large due to the friction effect between the turbine and the screw-type blades. The centrifugal compressor shows ideal comprehensive effects on the aspects of density, efficiency and density, and is one of the air pressurization modes which are considered to have the best development prospect at present. The high rotating speed, low vibration and oil-free lubrication are the requirements which must be met by a fuel cell compressor, and the fuel cell dedicated compressor becomes one of the bottlenecks which restrict the technical development of the fuel cell at present.
