The invention discloses a hydrogen fuel cell charging pile with an ejector. The hydrogen fuel cell charging pile comprises a fuel cell stack, the ejector, a gas delivery pump, a gas-water separator and a purging device. Wherein a cathode of the fuel cell stack is connected with the air supply device, an anode of the fuel cell stack is communicated with an outlet of the ejector, and an inlet of the ejector is connected with the hydrogen supply device. An outlet of the gas delivery pump is communicated with an inlet of the ejector, an outlet end of the gas-water separator is communicated with an inlet of the gas delivery pump, and an inlet end of the gas-water separator is communicated with an anode of the fuel cell stack. The outlet end of the gas-water separator is also communicated with the negative electrode of the fuel cell stack through the purging device, and a first control valve is arranged on a communication pipeline of the gas-water separator. According to the battery charging pile disclosed by the invention, the stability of the operation condition of the ejector is realized, and the problem that the work of the electric pile is influenced due to great influence on the ejector caused by unstable operation condition of a fuel cell is effectively solved.
