Claim:
1. An air humidification device for a fuel cell, comprising: an air compressor configured to supply air to a cathode of the fuel cell; and an injector disposed in an air supply line connected to an inlet of the air compressor to inject condensed water discharged from the fuel cell to the inlet of the air compressor using the bypassed compressed air from an outlet of the air compressor, wherein a bypass line that connects the outlet of the air compressor to an inlet of an injector includes a bypass valve configured to adjust an opening and closing angle, wherein the injector is a binary spray nozzle including: wherein a space between the outer hollow body and the inner hollow body of the injector is formed as a compressed air flow space which is communicatedly connected to the outlet of the air compressor by a bypass line, and an inner space of the internal hollow body is formed as a condensed water flow space which is communicatedly connected through a condensed water discharge line connected to a condensed water reservoir of the fuel cell.
