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...
