A diffuser for discharging hydrogen in a fuel cell vehicle is provided to enhance marketability by removing possibility of explosion due to a high hydrogen concentration by discharging backward flown hydrogen through both sides of a case unit. A diffuser(10) for discharging hydrogen in a fuel cell vehicle comprises a case unit(11), a hose unit(12), a sensor unit(13), and a fan operation unit(14). The hose unit transmits hydrogen gas from a fuel cell stack and a gas tank to the diffuser. The sensor unit measures a concentration of the hydrogen gas in the diffuser. The fan operation unit discharges the hydrogen gas in the diffuser through a fan(14a). The fan is a bidirectional rotation operation type to rotate even in a reverse direction through control of a control unit for adjusting a rotation direction of the fan operation unit by receiving a sensing signal of a current sensor for sensing an increase amount of power of the fan operation unit. |
