Functional module for refrigerant circuit of fuel cell system, method of manufacturing functional module, and container for refrigerant circuit of fuel cell system

摘要

A functional module for a coolant circuit of a vehicle fuel cell system includes a container having an ion-exchange material and a pump device for the coolant fluidically coupled to each other in such a manner that a coolant inlet and a coolant outlet of the pump device are connected to a coolant outlet and a coolant inlet of the container. The container surrounds at least one region of the pump device that has a conveying unit of the pump device at least in certain areas around the outer circumference.
