Zusammenfassung:	A computer-implemented method determines a degradation state of a turbo and/or a humidifier of a fuel cell system for a vehicle. The fuel cell system includes a fuel cell stack, the turbo and the humidifier. The method includes obtaining a fuel cell system efficiency value which corresponds to a measured efficiency decrease of the fuel cell system during use with respect to a first reference efficiency, obtaining a fuel cell stack efficiency value which corresponds to a measured efficiency decrease of the fuel cell stack during use with respect to a second reference efficiency, and determining the degradation state of the turbo and/or the humidifier based on a difference between the fuel cell system efficiency value and the fuel cell stack efficiency value.
