Abstract
A coolant bypass structure includes a main loop forming a channel in which coolant circulates; a bypass loop connected to the main loop and forming a selective bypass channel; and a stack bypass valve provided between the main loop and the bypass loop to open and close the bypass loop according to a predetermined temperature, and provided with an outlet temperature sensor. The coolant bypass structure may improve marketability by decreasing the starting time of the fuel cell vehicle in a frozen state and improve power efficiency.
