Disclosed is a fuel cell system (FCS) which comprises: a voltage measuring means (EC2) for measuring the open circuit voltage of an fuel cell (FC); a film thickness calculating means (EC3) for calculating the film thickness of a unit cell constituting the fuel cell (FC) on the basis of the difference between the theoretical electromotive voltage of the fuel cell (FC) and the open circuit voltage measured by the voltage measuring means (EC2); and an informing means (EC4) for informing of the case when the film thickness calculated by the film thickness calculating means (EC3) is equal to or less than a predetermined limit film thickness. |
