Abstract
A fuel cell system comprises a stack of electrochemical cells forming a fuel cell with an ion-exchange polymer membrane and a fuel gas supply circuit connecting a fuel gas reservoir to the anode of the fuel cell, the system being characterized in that it comprises: a hydrogen purge valve (305) installed on the anode outlet of the stack, a receiver (310) of the purged hydrogen, and means for redirecting the purged hydrogen to the anode inlet of the fuel cell. There is also an associated control method.
