1. A thermal management system for a fuel cell electric vehicle, comprising:
a stack cooling line configured to cool a fuel cell stack of the fuel cell electric vehicle;
a battery cooling line configured to cool a battery of the fuel cell electric vehicle;
a heat exchanger configured to exchange heat between a stack coolant of the stack cooling line and a battery coolant of the battery cooling line;
a valve configured to control an inflow of the stack coolant to the heat exchanger; and
a control apparatus configured to diagnose whether a component of the valve or the battery cooling line has failed when the battery has overheated, and to control a fuel cell output to cool the stack coolant and cool the battery by using a temperature of the stack coolant when a failure of the valve or a component failure of the battery cooling line occurs.
