The invention provides a flow-adjustable fuel cell engine hydrogen subsystem, and belongs to the field of fuel cells. The flow-adjustable fuel cell engine hydrogen subsystem comprises a proportional pressure regulating valve, an adjustable ejector, an electric pile, a hydrogen-water separator, a hydrogen discharging electromagnetic valve, a water discharging electromagnetic valve, an adjustable ejector valve, a hydrogen-water separator controller and a hydrogen subsystem controller. In an operation process of a fuel cell engine, a proportional control valve opens at different angles to controla flow according to different power, and the adjustable ejector is controlled by changing an original Rafael tube cavity through movement of a valve body according to the required flow by utilizing acceleration and deceleration effects of the Rafael tube. In order to reduce resistance of an ejection flow as much as possible, the hydrogen-water separator and the adjustable ejector enter a galvanicpile to participate in a
