The invention relates to a computer-implemented method for estimating a state of health of a humidifier (20) of a fuel cell system (1) for a vehicle (100), comprising:- in response to determining that a predefined condition for vehicle onboard measurements is fulfilled:- performing (S1) 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 (1) are performed, wherein a step increase is indicative of an instantaneous power increase of the fuel cell system (1), and- fitting (S2) the measured parameters in a humidifier aging model and therefrom estimating (S3) the state of health of the humidifier (20). The invention also relates to a fuel cell system (1), a vehicle (100), a computer program and a computer readable medium.
