Abstract
A method and system are disclosed for reducing the consumption of safety gas in a fuel cell system having at least one fuel cell unit whose fuel cells include an anode side and a cathode side, as well as an electrolyte interposed therebetween. A supply is provided for supplying the anode with a safety gas, and an exhaust is provided for exhausting the fuel cell unit of a spent safety gas coming from the anode side. The method can adapt a specific percentage of the spent safety gas flow coming from the anode side of the fuel cells to be re-supplied into the anode side of the fuel cells.
