The invention relates to a computer-implemented method for estimating the state of health of a humidifier (20) of a fuel cell system (1) of a vehicle (100), comprising:-in response to determining that predefined conditions of a vehicle on-board measurement are satisfied:-performing (S1) a step response measurement, comprising measuring parameters relating to a dynamic response of water mass delivery and heat delivery of the humidifier when a step increase of the fuel cell system (1) is performed, where the step increase indicates an instantaneous power increase of the fuel cell system (1); and-fitting (S2) the measured parameters into the humidifier aging model and estimating (S3) therefrom 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.

    本发明涉及一种用于估计车辆(100)的燃料电池系统(1)的加湿器(20)的健康状态的计算机实施的方法,其包括:‑响应于确定满足车辆车载测量的预定义条件:‑执行(S1)阶跃响应测量,包括当执行燃料电池系统(1)的阶跃增加时测量与加湿器的水团输送和热量输送的动态响应相关的参数,其中阶跃增加指示燃料电池系统(1)的瞬时功率增加;以及‑将测量的参数拟合(S2)到加湿器老化模型中,并由此估计(S3)加湿器(20)的健康状态。本发明还涉及一种燃料电池系统(1)、一种车辆(100)、一种计算机程序以及一种计算可读介质。
