SYSTEM AND METHOD OF DRAINING RESIDUAL WATER OF A FUEL CELL FOR A VEHICLE

A system and a method of draining residual water of a fuel cell for a vehicle are proposed. The system includes a fuel cell; an outdoor temperature sensor measuring an outdoor temperature; a drainer draining residual water in the fuel cell; and a controller previously controlling the drainer to drain the residual water in the fuel cell before parking of the vehicle is completed or an operation of the fuel cell is terminated, when a parking available situation is detected during driving of the vehicle in a state where the outdoor temperature is equal to or less than a reference temperature.
