Abstract
A device for preventing over pressure of a cooling system of a fuel cell system is provided. The device detects a change in a temperature of a coolant discharged from a fuel cell stack and prevents over pressure of the cooling system before pressure of the coolant is elevated by the increase in the temperature. In particular, a coolant pump circulates a coolant to a fuel cell stack, a radiator radiates heat absorbed in the coolant, and a temperature sensor detects a temperature of the coolant discharged from the fuel cell stack the device. The system further includes an electronic valve mounted in a pillar neck of the radiator connected with a reservoir for supplementing a coolant to open and close the pillar neck and a fuel cell controller that operates the electronic valve based on a signal of the temperature sensor.
