- the protective cover comprises at least one sealing element, which on a port having the opening of the
- Refrigerant container pushed and / or inserted into this and / or
- Such a sealing element integrated in the protective cover makes it possible to seal off the opening of the coolant reservoir when introducing the module into the coolant reservoir in a particularly simple manner.
- a contamination of the coolant is at least largely in a method for introducing a
- a coolant container for a fuel cell system in which an opening in the coolant container is released, and wherein by means of a protective cover of the module when introducing the module into the coolant container, the opening to an environment of the
- Coolant tank is sealed towards.
- the module protecting the module from contamination can serve as transport packaging, which is then used during transport
- the protective cover after the introduction of the module in the coolant tank of the coolant tank, in particular by removing or unscrewing, is removed.
- the protective cover has fulfilled its function after the introduction of the module into the coolant tank and then does not interfere further when it is removed from the coolant tank.

- Fig. 1 shows a detail of a container assembly 1 for a fuel cell system.
- the container assembly comprises a coolant container 2, which serves as a reservoir for a coolant for cooling a fuel cell stack of the fuel cell system.
- a nozzle 3 is shown in Fig. 1, which limits an insertion opening 4.
- the insertion opening 4 is dimensioned such that an ion exchange module 5 can be introduced into the coolant container 2 via this.
- the ion exchange module 5 comprises a cylindrical container 6, in which an ion exchange material 7 is accommodated.
- the ion exchange module 5 is surrounded by a protective cover 8, which protects the ion exchange module 5 against contamination during transport.
- a bottom 9 of the protective cover 8 is, for example by tearing, separated from the protective cover 8. The separation of the bottom 9 is illustrated in Fig. 1 by a movement arrow 10.
- the protective cover 8 also has a sealing ring 11, which after the separation of the bottom 9 can be pushed onto the neck 3 of the coolant container 2.
- FIG. 2 shows the container arrangement 1, in which the protective cover 8 for the ion exchanger module 5 is pushed onto the neck 3 of the coolant container 2. This seals the Sealing ring 11, the insertion opening 4 of the coolant tank 2 to a vicinity of the coolant tank 2 towards contamination-tight.
- Coolant container 2 by pushing the sealing ring 11 may be provided that the protective cover 8 can be screwed onto the neck 3.
- the sealing ring 11 may be guided in an internal thread or in an external thread of the nozzle 3.
- guide rails 12 are provided on the coolant tank, which ensure that the ion exchange module 5 can be placed in the correct position in the coolant tank 2.
- a lid 13 of the ion exchange module 5 limits the introduction of the
- Lonen storageermoduls 5 in the coolant tank 2 in the direction of the arrow 14 shown in Fig. 2 by the lid 13 runs on the - then acting as a stop - guide rails 12 runs.
- the lid 13 may be provided on the ion exchanger module 5, a different kind stop.
- the lid 13 can serve directly the contamination-tight closure of the nozzle 3, as soon as the protective cover 8 is removed from the coolant container 2 as by peeling or unscrewing (see Fig .. 3).
