Abstract
A process for operating a fuel cell system (2) arranged in a vehicle (1), in which process a foreseeable travel time duration and/or a foreseeable travel time end point are communicated to a control device (4) of the fuel cell system (2) at the beginning of a travel of the vehicle (1) or during the travel. The control device (4) operates the fuel cell system (2) such that a switch-off procedure for switching off the fuel cell system (2) is started so far ahead of the foreseeable end of the travel in time that the switch-off procedure will have been completed extensively simultaneously with the foreseeable end of the travel and the fuel cell system (2) is switched off.
Claims20
A process for operating a fuel cell system arranged in a vehicle, the process comprising:
- communicating one or more of a foreseeable travel time duration and a foreseeable travel time end point to a control device of the fuel cell system at the beginning of a travel of the vehicle or during the travel;
- operating the fuel cell system with the control device such that at least one of:
- a switch-off procedure for switching off the fuel cell system is started in time, before the foreseeable end of travel, such that the switch-off procedure will have taken place completely extensively simultaneously with the foreseeable end of travel and the fuel cell system is switched off or brought into a standby mode;
- and
- a switch-on procedure for switching on the fuel cell system is started in time, before the foreseeable end of travel, such that the switch-on procedure will have taken place completely extensively simultaneously with the foreseeable end of travel and the fuel cell system is switched on or brought into a standby mode.
A motor vehicle comprising:
- a fuel cell system;
- a control device for operating the fuel cell system, one or more of a foreseeable travel time duration and a foreseeable travel time end point being communicated to the control device of the fuel cell system at the beginning of a travel of the vehicle or during the travel, the control device activating a switch-off procedure for switching off the fuel cell system or a switch-on procedure for switching on the fuel cell system based on a foreseeable end of travel in time such that the procedure will have been completed extensively simultaneously with the foreseeable end of travel and the fuel cell system is switched off or switched on or brought into a standby mode.
