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.
