Fuel cell vehicle

A method of cooling a fuel cell vehicle including a heat source configured to discharge a cooling water used for generation of power and a radiator fluidically connected to the heat source and configured to dissipate heat from the cooling water used for cooling of the heat source to an outside thereof, the radiator including areas including different temperatures, the method comprising:

• checking, by a controller, an internal condition or an external condition of the vehicle;
• spraying, by the controller, a first spray liquid to a first area having a first temperature of the different temperatures among the areas when the controller concludes that an outside air temperature of the vehicle and a temperature of the cooling water satisfy a first condition based on a result of checking the internal condition or the external condition of the vehicle,
• wherein the first condition is as follows:
• TO
• ≥
• T
• ⁢
• 1
• ⁢
• and
• ⁢
• TC
• ≥
• T
• ⁢
• 2
• where T0 represents the outside air temperature, T1 represents a first predetermined outside air temperature, TC represents the temperature of the cooling water, and T2 represents a first predetermined cooling temperature;
• and
• spraying, by the controller, a second spray liquid including a lower temperature than the first spray liquid to a second area including a second temperature, which is lower than the first temperature, among the areas when the controller concludes that the outside air temperature of the vehicle and the temperature of the cooling water satisfy a second condition based on a result of checking the internal condition or the external condition of the vehicle, and
• wherein the second condition is as follows:
• T
• ⁢
• 4
• ≤
• T
• ⁢
• O
• ≤
• T
• ⁢
• 3
• ⁢
• and
• ⁢
• T
• ⁢
• 6
• ≤

• ⁢
• C
• ≤
• T
• ⁢
• 5
• where T3 represents a second predetermined outside air temperature, T4 represents a third predetermined outside air temperature, T5 represents a second predetermined cooling temperature, and T6 represents a third predetermined cooling temperature.
