Abstract
A method for determining aging of a fuel cell system for a vehicle, comprising identifying a future interval in terms of time or distance during which the fuel cell system is expected to operate at stationary operating conditions, obtaining measurement values pertaining to at least one fuel cell parameter indicative of degradation of the fuel cell system during the identified interval, and determining an aging state of the fuel cell system using the measurement values.
Claims16
A method for determining aging of a fuel cell system for a vehicle, comprising:
- during operation of the vehicle, identifying a future interval in terms of time or distance, during which interval the fuel cell system is expected to operate at stationary operating conditions, and during which interval the fuel cell system is expected to be operated at a constant or nearly constant operating power,
- obtaining measurement values pertaining to at least one fuel cell parameter indicative of degradation of the fuel cell system during the identified interval only, and
- determining an aging state of the fuel cell system using the measurement values.
