EXPANSION TANK FOR LIQUID FLUID AND ION EXCHANGER OF AN EXPANSION TANK

摘要

The invention relates to an expansion tank (10) for liquid fluid, in particular cooling fluid of a cooling device of a functional system, in particular of a fuel cell system, in particular of a motor vehicle, comprising at least one fluid inlet (36) and at least one fluid outlet (48) for the fluid. An ion exchanger (25) for processing the fluid comprises an ion exchanger tank (26). The ion exchanger tank (26) comprises at least one inlet (41) for fluid to be processed and at least one outlet (43) for processed fluid. In the ion exchanger tank (26), a granular ion-exchange medium (27) is arranged between the inlet (41) and the outlet (43) with respect to the flow. The ion exchanger tank (26) is arranged in the expansion tank (10) in such a way that the ion exchanger tank can be replaced. The inlet (41) corresponds to the fluid inlet (36) and the outlet (43) corresponds to the fluid outlet (48). The ion exchanger tank (26) has a flexible casing.
