Abstract
A cooling arrangement for cooling a fuel cell in a fuel cell system is disclosed. The cooling arrangement has at least two fluidically connected cooling circuits in which a liquid coolant medium flows, The first cooling circuit includes a first coolant pump, a fuel cell heat exchanger, a heating unit, and a charge air cooler, which is in heat-exchanging contact with compressed supply air flowing to the fuel cell. The second cooling circuit includes a cooling heat exchanger for cooling the liquid coolant medium. The cooling arrangement includes at least one further coolant pump.

A cooling arrangement for cooling a fuel cell in a fuel cell system, comprising:
- a first cooling circuit and a second cooling circuit, wherein the first and second cooling circuits are fluidically connected and wherein a liquid coolant medium flows in the first and second cooling circuits;
- wherein the first cooling circuit includes a first coolant pump, a fuel cell heat exchanger, a heating unit, and a charge air cooler which is in heat-exchanging contact with compressed supply air flowing to the fuel cell;
- wherein the second cooling circuit includes a cooling heat exchanger for cooling the liquid coolant medium;
- a second coolant pump;
- wherein a heating heat exchanger for heating a component assigned to the heating heat exchanger and/or for heating a medium flowing through the heating heat exchanger is disposed before the fuel cell heat exchanger in a flow direction;
- wherein an ion exchanger is disposed in parallel to the heating heat exchanger with respect to a through flow with the liquid coolant medium.
