1. A system for humidifying a vehicle, the system comprising:
a fuel cell stack for producing electrical energy through an electrochemical reaction of hydrogen and oxygen;
a water supply tank for storing water generated during electricity generation in the fuel cell stack;
a first humidifier for humidifying an interior of the vehicle using the water supplied from the water supply tank;
a heating apparatus for applying heat to a vehicle glass; and
a controller configured to perform anti-fogging control of the vehicle glass using the heating apparatus when humidifying the interior of the vehicle;
wherein the controller is further configured to:
determine a target surface temperature based on a difference between a dew point temperature and an outside air temperature;
measure a window surface temperature using a surface temperature sensor after operating the heating apparatus;
compare the window surface temperature with the target surface temperature; and
start humidification of the interior of the vehicle at a time point when the window surface temperature reaches the target surface temperature.
