The present invention relates to a cooling water tank for a fuel cell system. The cooling water tank includes a cartridge to prevent the cooling water from leaking due to the abnormal shortage and expansion of the cooling water in advance. The present invention also can enhance the relevant technology through reducing maintenance points within the system and simplifying the cooling water tank structure. According to the present invention, the cooling water tank, which includes the cartridge and is used in the fuel cell system, includes: a cooling water tank body storing the cooling water; a cooling water tank cover which covers the upper surface of the cooling water tank and includes a circular opening; the cartridge which is inserted through the circular hole and mounted to the cooling water tank cover and stores the cooling water to adjust the water level in the cooling water tank body; a cooling water outlet which is formed on a side of the cooling water tank body and discharges the cooling water to a fuel cell stack; and a cooling water inlet which is formed on a side of the cooling water body and draws the cooling water heated in the heat exchange process in the fuel cell stack into the cooling water tank body. |
