A method for controlling the moisture of gas for a fuel cell and its device, are provided to obtain more precise humidity of a fuel cell by preventing the condensation of moisturized fuel gas during movement. The method comprises the steps of (S200) setting the humidity of a fuel cell corresponding to the temperature of the second position adjacent to the entrance of a fuel cell; (S230) setting the first position adjacent to the discharge hole of a fuel gas moisturization part to be higher than that of the second position and reducing the set humidity of the fuel gas into the humidity of the target temperature; (S240) controlling the temperature of the first position to be maintained at the target temperature; (S250) controlling the humidity of the first position to be maintained at the reduced humidity; and (S260) controlling the temperature of the second position to be maintained at the set temperature. |
