Regeneration unit, fuel cell control device, fuel cell stack, and method for regenerating a fuel cell stack

A fuel cell (11) having a fuel cell control device (20) with a fuel cell monitoring unit (15) and a regeneration unit (10) that includes

• a detection unit (12) for detecting surroundings data (18) and/or operating data (19) of the at least one fuel cell (11) and/or of the motor vehicle;
• a monitoring unit (13) configured to determine and/or anticipate a coasting mode of the motor vehicle based on the detected surroundings data (18) and/or the detected operating data (19);
• and
• a fuel cell interface (14) configured to be connected to a fuel cell monitoring unit (15) of a fuel cell control device (20), wherein the fuel cell interface (14) is configured to forward the determined and/or anticipated coasting mode from the monitoring unit (13) of the regeneration unit (10) to the fuel cell monitoring unit (15) of the fuel cell control device (20) for carrying out a regeneration process of the at least one fuel cell (11),
• wherein the fuel cell monitoring unit (15) and the regeneration unit (10) are connected to each other so as to exchange data via a fuel cell interface (14), and wherein the fuel cell monitoring unit (15) is configured to perform a regeneration process of the at least one fuel cell (11) on the basis of the determined and/or anticipated coasting mode of the motor vehicle by means of the regeneration unit (10).
