Problems solved by technology
However, the existing technology is still unable to accurately simulate the inlet gas parameters of the hydrogen circulating pump when the fuel cell system is operating under complex working conditions, resulting in inaccurate performance data of the hydrogen circulating pump under different working conditions. The applicability and matching of the hydrogen circulation pump cannot be accurately judged before the system test, and reliable data support cannot be provided for the subsequent design and optimization of the hydrogen circulation pump
