Operating process for a fuel cell system

A process comprising:

• providing a vehicle comprising at least one electrical component, a tachograph and an internal combustion engine;
• providing an operating a fuel cell system comprising a control device, said control device being connected to said tachograph, said fuel cell system being arranged in said vehicle, said fuel cell system for providing power to said at least one electrical component during operating breaks, with said internal combustion engine switched off, the fuel cell system having a fuel cell system start procedure, to provide some protection of fuel cell system components against thermal and mechanical stress prior to fuel cell operation;
• providing a foreseeable operating break start time of an operating break as output via said tachograph, said foreseeable operating break start time corresponding to a point in time at which the internal combustion engine is switched off, said control device receiving said foreseeable operating break start time as input;
• and
• determining a system start time for the fuel cell system for said operating break via said control device such that the start procedure of the fuel cell system ends at the foreseeable break start time and the fuel cell system is ready for operation when the fuel cell system is started at the determined system start time.

A process comprising:

• providing a vehicle comprising at least one electrical component, a tachograph and an internal combustion engine, said tachograph determining a foreseeable break start time of an operating break, said foreseeable break start time corresponding to a point in time at which the internal combustion engine is switched off following a drive mode during which the internal combustion engine is switched on;
• providing an operating a fuel cell system comprising a control device, said control device being connected to said tachograph, said fuel cell system being arranged in said vehicle, said fuel cell system for providing power to said at least one electrical component during operating breaks, when said internal combustion engine is in an off state, the fuel cell system having a fuel cell system start procedure, to provide some protection of fuel cell system components against thermal and mechanical stress prior to fuel cell operation;
• providing said foreseeable break start time to said control device as input with said fuel cell system in an inactive state;
• determining a system start time for the fuel cell system for said foreseeable operating break via said control device;
• and
• ending the fuel cell start procedure of the fuel cell system at the foreseeable break start time and providing the fuel cell system in an operational state at the determined system start time.
