Abstract (en)

[origin: WO2012062433A1] The invention relates to a coolant circuit (3) for a fuel cell system, in particular of a vehicle (1), wherein an ion exchanger material (4) is disposed in at least one component (5, 6) of the coolant circuit (3) through which coolant flows during cooling mode. The ion exchanger material (4) is thereby fixed to an inner face (7) of a wall of the at least one component (5, 6). During changing out of the ion exchanger material (4), the entire component (5, 6) is changed out and replaced with a replacement component (12, 13). The invention further relates to a method for changing out ion exchanger material (4) in a coolant circuit (3) for a fuel cell system.
