【Abstract】Aimingat the problemof weak ejectorabilityof vehicle fuelcellanodecycleejectorinlowpowersegment， thispaperanalyzes pulseejectorcycle performancebasedonavehicle fuelcellFirstly，thecomponentparametersofanode cycle mixtureare testedby bench，and then theequivalent model and pulse ejector model offuelcellanodecycleare established.Thecharacteristicsofpulseejectionunderdiferentpulseperiodandcurrntdensityarestudied.Theresultsshow thatunderdiferentcurrent densities，theproportionof hydrogen in thereflux mixture is between82.2%and93.6%，the proportion of nitrogen is between 1.35% and 7.68% ，and the relative humidityis between 82% and 95 % .Compared with conventional ejectors，the average metering ratio of pulse ejectors is increased by 20%～70% at low and medium power，and the average metering ratio increases with the increase of pulse frequency and current density.
