Recycling loop for a gas circuit of a fuel cell stack, forming a connecting line beginning at the outlet of one of the two anode or cathode circuits and terminating in one of the two supply circuits, either in the fuel gas supply channel, or in the oxidant gas supply channel, providing the recycling of the gas contained in the anode or cathode circuits of the fuel cell stack, and comprising a pump that provides the recycling of the gas contained in the anode or cathode circuits of the fuel cell stack, a multi-way valve dividing said recycling loop into a first section and a second section, said multi-way valve having a first stable usage position providing the continuity between the first and second sections of said recycling loop and having a second stable usage position simultaneously providing the interruption of said continuity between the first and second sections of said recycling loop and a bringing of said recycling loop into contact with the atmosphere carried out by manoeuvring said multi-way valve. |
