Abstract

The invention discloses a centrifugal compressor and a hydrogen fuel cell system. The centrifugal compressor comprises a machine shell, a rotating shaft, an impeller, a motor assembly, a first volute,a turbine, a second volute and a heat exchanger, wherein the machine shell is equipped with a first cooling medium flow path; the rotating shaft penetrates through the machine shell; the impeller isconnected with one end of the rotating shaft; the motor assembly comprises a rotor and a stator; the rotor is connected with the rotating shaft; the stator is arranged on the outer side of the rotor and connected with the machine shell; the first volute is connected with the machine shell and covers the outer side of the impeller; a first air inlet and a first air outlet are arranged on the firstvolute; the turbine is connected with the other end of the rotating shaft; the second volute is connected with the machine shell and covers the outer side of the turbine; a second air inlet and a second air outlet are arranged on the second volute; a second cooling medium flow path is arranged inside the heat exchanger and communicates with the first cooling medium flow path; the heat exchanger isequipped with a penetrating airflow channel; and the airflow channel communicates with the second air outlet. The hydrogen fuel cell system comprises an electric pile and the centrifugal compressor.By the adoption of the technical scheme, the energy utilization rate can be higher and the service life can be prolonged.

Description

technical field [0001] The invention is used in the field of hydrogen fuel cells, and in particular relates to a centrifugal compressor and a hydrogen fuel cell system. Background technique [0002] In order to obtain high power density and performance, hydrogen fuel cells must work under relatively high gas pressure. Therefore, an air compressor with high efficiency and high compression ratio is required to provide high-pressure air for the fuel cell. At present, the compressors used in hydrogen fuel cells mainly include Roots type, scroll type, screw type and centrifugal type. Among them, the centrifugal compressor has compact structure, small size, light weight, significantly reduced vibration and noise, and represents the future development direction of hydrogen fuel cell compressors. [0003] The high-pressure gas compressed by the centrifugal compressor passes through the stack of the hydrogen fuel cell to provide the environmental conditions for power generation, and...
