چکیده
The aerodynamic performance improvement of radial impellers is positive significance to improve the overall hydrogen fuel cell systems (FCS). Our team proposes a multi-degree-of-freedom (MDOF) surface parameterization method for global automatic optimization impeller aerodynamics. MDOF characterized by fewer variables, construction ease, smoothness, good flexibility, and blade strength maintenance. In this paper, 100-kW stack optimized, showing isentropic efficiency increase 0.7%, flow rate 3.77%, total pressure ratio 0.37%. results revealed that optimized significantly improved, verifying validity reliability proposed novel design providing technical support methodological research FCS.
