This utility model belongs to the field of hydrogen fuel cell technology and relates to an ejector assembly with a pressurization function. It includes an ejector body, a return valve body installed on the top of the ejector body, and the inner cavity of the return valve body communicating with the return port at the top of the ejector body. A turbine fan is rotatably mounted inside the return valve body to compress the fuel cell return gas flowing back to the return valve body. A solenoid valve is installed at the inlet end of the ejector body, and a nozzle is installed on the solenoid valve. The nozzle extends into the mixing chamber of the ejector body, and the nozzle outlet extends to the gas channel inlet end of the ejector body. This assembly can effectively improve the intake efficiency of the return hydrogen gas, and has high structural reliability and is easy to maintain.
