Abstract
The invention relates to a supply circuit of the cathode (250) of at least one electrochemical cell (200) of the PEMFC type, which further comprises a membrane (290) separating an anode (210) and said cathode (250), with this circuit comprising:
- a supply channel (220) comprising an inlet (282) and making it possible to convey a fluid (90) in contact with the cathode (250);
- a discharge channel (280) that makes it possible to remove gases from the cell,
- a recirculation channel (100, 100′), comprising:
- a first opening (102) connected to the outlet (284) of the discharge channel (280);
- a second opening (104) connected to the inlet (282) of the supply channel (280), by the intermediary of a connector (80);
- a third opening (106) and means for removing (140) that allow at least one portion of the fluid (90) to be removed from the recirculation channel by the third opening (106),
- the recirculation channel (100, 100′) and/or the supply channel further comprising at least one compressor (C1, C2), which makes it possible to control the flow rates and/or the proportion of the fluids to be mixed in the connector.

18. Supply circuit of the cathode of at least one electrochemical cell of the PEMFC type, which further comprises a membrane separating an anode and said cathode, with this circuit comprising:
-
a supply channel comprising an inlet and which makes it possible to convey a fluid in contact with the cathode; a discharge channel that makes it possible to remove gases from the cell, a recirculation channel delimited by a wall at least partially sealing the fluid, comprising; a first opening connected to the outlet of the discharge channel; a second opening connected to the inlet of the supply channel, by the intermediary of a connector, said connector further making it possible to convey a combustion agent fluid to the cathode, which mixes with the fluid exiting from the recirculation channel by the second opening; a third opening and a movable sealing member allowing at least one portion of the fluid to be removed from the recirculation channel by the third opening, the recirculation channel and/or the supply channel further comprising at least one compressor, which makes it possible to control the flow rates and/or the proportion of the fluids to be mixed in the connector. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
