Abstract

A method for enabling a fuel cell system includes the steps of: i) detecting a pressure value, which is indicative of the pressure within a section of the anode sub-system, wherein the section begins downstream of a pressure reducer; ii) relieving the pressure of the section during a pressure relief time interval, if the pressure value is greater than a pressure limit value and a release request is present; and then iii) enabling the fuel cell system if the pressure value in the section after the pressure relief is less than the pressure limit value.
