A two-way variable nozzle ejector for a fuel cell is provided to improve the recycling efficiency of fuel by the variable respond to the change of the operation condition of a fuel cell. A two-way variable nozzle ejector comprises at least two nozzles for control the flux and flow rate on the channel of a suction chamber, and a needle for allowing the axis to be controlled respectively in the each nozzle, thereby allowing the cross-sectional area of the axis of the nozzle to be varied. Also the two-way variable nozzle ejector comprises a suction chamber(110) having a channel(113); a first nozzle(120); a first needle(130) for varying the axis cross-sectional area of the first needle; a second nozzle(140); and a second needle(150) for varying the axis cross-sectional area of the second needle.
