Abstract
A method for the start preparation of a fuel cell system in a vehicle having a fuel cell and a system bypass where an air flow is conveyed by parts of the fuel cell system in order to dry the fuel cell. In a first temporal phase of the method, a larger part of the air flow is led through the fuel cell and a smaller part of the air flow is led through the system bypass, after which, in a second temporal phase, a larger part of the air flow is led through the system bypass and a smaller part of the air flow is led through the fuel cell.
Claims9
A method of a start preparation routine of a fuel cell system in a vehicle, wherein the fuel cell system has a fuel cell and a system bypass, comprising the steps of:
- conveying a larger part of an air flow through the fuel cell and a smaller part of the air flow through the system bypass in a first temporal phase;
- and
- conveying a larger part of the air flow through the system bypass and a smaller part of the air flow through the fuel cell in a second temporal phase which is after the first temporal phase;
- wherein a heating device in the fuel cell system is operated before the first temporal phase in a pre-switched heating phase.
