PURPOSE: A bubble exhausting device of an ion filter is provided to quickly exhaust bubbles in cooling water which flows through a cooling loop, thereby improving the heat radiating performance for a fuel cell. CONSTITUTION: A bubble exhausting device(30) of an ion filter comprises as follows: a coupling unit(32) with a vertical screw hole which is formed on the top side of a cover cap(24) mounted in the upper side of an ion filter(10); an air bubble discharge hole(33) which is horizontally formed in the lower part of the coupling unit and connected to the vertical screw hole; and a screw(33) with an upper screw part which is screw-coupled to the vertical screw hole of the coupling unit and a lower opening unit which opens and closes the air bubble discharge hole. |
