| Zusammenfassung: | A computer-implemented method estimates a state of health of a humidifier of a fuel cell system for a vehicle. The method includes in response to determining that a predefined condition for vehicle onboard measurements is fulfilled: performing step response measurements, comprising measuring parameters related to dynamic response of water mass transport and heat transport of the humidifier when step increases of the fuel cell system are performed, wherein a step increase is indicative of an instantaneous power increase of the fuel cell system, and fitting the measured parameters in a humidifier aging model and therefrom estimating the state of health of the humidifier. |
