Fuel cell cooling system

A fuel cell cooling system comprising:

• a fuel cell module including a fuel cell stack;
• a cooling module including a cooling tower in which cooling fluid is accommodated, the cooling module being configured to adjust a temperature of the fuel cell module;
• a heat exchanger configured to exchange heat between first circulation cooling water circulating in the fuel cell module and second circulation cooling water circulating in the cooling tower;
• a condensate supply line connected to the cooling tower to supply, to the cooling tower, water generated in a power generation process of the fuel cell module;
• a cooling pump configured to adjust a flow rate of the water supplied to the cooling tower;
• and
• a controller configured to control operation of the cooling pump;
• wherein the fuel cell module further includes a first cooling water line through which the first circulation cooling water for adjusting a temperature of the fuel cell stack circulates;
• wherein the cooling module further includes a second cooling water line through which second circulation cooling water cooled by the cooling fluid circulates;
• and
• wherein the second cooling water line includes:
• an inlet line provided such that the second circulation cooling water heat-exchanged by the heat exchanger is introduced into the cooling tower and having a first temperature sensor;
• and
• an outlet line provided such that the second circulation cooling water cooled by the cooling tower is discharged to the heat exchanger and having a second temperature sensor;
• and
• wherein the controller controls the operation of the cooling pump by comparing a difference value between a first temperature measured by the first temperature sensor and a second temperature measured by the second temperature sensor.
