Proton exchange membrane fuel cell (PEMFC) vehicles are considered the ultimate form of automotive development due to their zero emissions and high energy conversion efficiency. The hydrogen supply system is crucial to the operation of PEMFC vehicles; efficient hydrogen supply improves hydrogen utilization, increases the hydrogen equivalence ratio, and reduces water blockage on the anode side. Ejectors, with their simple structure, small size, and no parasitic power, have attracted widespread attention. This paper establishes an automatic simulation platform for coaxial nozzle ejectors to study the impact of different operating conditions on ejector performance, and compares the working performance of coaxial nozzle ejectors with traditional single-nozzle ejectors under different loads.
