  • COOLANT CYCLE FOR A FUEL CELL SYSTEM AND METHOD FOR OPERATING A COOLANT CYCLE
    Publication number: 20140072894
    Abstract: A coolant circuit (1) for a fuel cell system of a vehicle. Coolant (10) is able to flow through a coolant line (3) in the cooling operation, and an ion exchanger module (4) can be fluidically coupled with the coolant line (3). The coolant circuit (1) has at least one closing element (8), formed to close the coolant line (3). The closing of the same via the at least one closing element (8) is effected by an uncoupling of the ion exchanger module (4) from the at least one coolant line (3). Furthermore, the invention relates to a method to operate the coolant circuit (1).
