| 摘要 |
The invention relates to a supply circuit of the cathode (250) of at least one PEMFC electrochemical cell (200) which comprises, in addition, a membrane (290) separating an anode (210) and said cathode (250), said circuit including: - a feed channel (220) comprising an inlet (282) and making it possible to bring a fluid (90) into contact with the cathode (250); - a delivery channel (280) for removing the gas from the cell, - a recirculation channel (100, 100'), comprising: a first opening (102) connected to the outlet (284) of the delivery channel (280); a second opening (104) connected to the inlet (282) of the feed channel (280), via a connector (80); a third opening (106) and removal means (140) making it possible for at least a portion of the fluid (90) to be removed from the recirculation channel through 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. |
