ABSTRACT:
The present invention provides a cooling system of fuel cell, which solves the gas biting noise problem by trapping bubble in a coolant, gives protection to a stack (MEA) and the membrane of a humidifier by regulating the coolant pressure of fuel cell and improves the life of a ion exchanger by preventing foreign materials (carbonate ion etc.) from dissolving into the coolant.
