Zusammenfassung:	Disclosed are a device and method for detecting the coolant level in a thermal management system for a fuel cell vehicle, which can accurately and rapidly detect the lack of coolant using a detection value of a pressure sensor. That is, the present invention provides a device and method for detecting the coolant level in a thermal management system for a fuel cell vehicle, which can accurately and rapidly monitor the lack of coolant by calculating in real time the lack of coolant based on a change in slope value and a change in amplitude of a detection value of a pressure sensor according to the flow of coolant while the pressure sensor is mounted in a coolant line connected to an inlet of a fuel cell stack and a reservoir is connected to a pressure cap of a radiator.
