PURPOSE: A fuel cell cooling system is provided to detect bubbles in cooling water in real time, thereby obtaining cooling efficiency of the fuel cell stack and stability of the system. CONSTITUTION: A fuel cell cooling system(100) comprises a coolant tank(10) which stores cooling water, a coolant pump(30) which transfers the cooling water to a fuel cell stack(1) through a coolant supply line(3) and circulates the cooling water to the coolant tank through a radiator(5), a bypass line(50) which interlinks upper side of the coolant supply line and the coolant tank, and an air bubble sensor(70) which detects bubbles in cooling water and outputs the detected signal to a controller(90). |
