  "textContent": "A control system for fuel cell cooling is provided. The system includes a fuel cell stack, a coolant circulation line connected to the fuel cell stack, and a heat exchange device provided in the coolant circulation line. A bypass line bypasses the heat exchange device. A temperature adjusting device adjusts a ratio between coolant flowing into the heat exchange device of the coolant circulation line and coolant flowing into the bypass line. A temperature estimator estimates a temperature of the coolant of the coolant circulation line at a point before the bypass line joins the coolant circulation line after the coolant passes through the heat exchange device. An opening degree controller operates the temperature adjusting device using the temperature of the coolant estimated by the temperature estimator and the temperature of the coolant at a point at which the coolant flows into the fuel cell stack.",
