摘要：
For a 120kW hydrogen fuel cell system, a centrifugal air compressor with fixed power of 22kW fuel cell is designed. Firstly, the theoretical calculation is carried out for the aerodynamic characteristics of a ultra-high-speed permanent magnet synchronous motor, an air compressor, and an aerodynamic foil bearing. Then, a prototype is trial-produced and a related test bench is built for test verification. Finally, both the simulation and test results indicate that the designed centrifugal air compressor meets the overall requirements of the hydrogen fuel cell system, and the relevant conclusions provide both theoretical and experimental references for the subsequent series development and design of the centrifugal air compressor.
