Abstract (en)
[origin: FR2881577A1] The system has control units (44, 45) respectively controlling hydrogen supplied to an anode (A) of a fuel cell (1) and oxygen supplied to a cathode (C) of the cell. The units (44, 45) are respectively apt to adapt hydrogen and oxygen over-stoichiometry based on power needed at the cell. The control units constantly and increasingly maintain the over-stoichiometry if current density needed at the cell is lower than respective values. An independent claim is also included for a fuel cell system control method.
