  • Patent number: 12021282
    Abstract: A fuel cell and a method for regenerating this fuel cell, including a supply of the fuel cell by the main supply conduit by a fluid having a nominal flow rate and a nominal molar fraction of combustion agent, during a regeneration phase of a given group, a switching of the inlet, outlet and recirculation switches of the fluid circuit so as to supply the given group from the recirculation line of the given group and from a fluid discharge line of at least one other group, an application of a regeneration voltage Ve to the cells of the given group, Ve being less than or equal to 0.3V.

  • Publication number: 20240162460
    Abstract: A method may activate a fuel cell including a plurality of electrochemical cells in a stack, the fuel cell being intended to operate, during at least one nominal operating phase, as an electric generator. Such a method may include, during an activation phase by electrolysis, prior to the at least one nominal operating phase: electrically supplying the fuel cell by an external electric generator, the electric supply being configured to apply an activation voltage greater than the voltage of the cell in an open circuit (OCV); fluid supplying a humid gas fluid at a first electrode and/or a second electrodes. The humid gas may have a relative humidity (RH) such that 40%?RH<100%. The fuel cell may operate in electrolysis during the activation phase called by electrolysis.

  • Patent number: 10686202
    Abstract: A method is provided for determining a spatial distribution (Rx,yf) of a parameter of interest (R) representative of the electrical power production of an electrochemical cell, including steps of determining the spatial distribution (Rx,yf) the parameter of interest (R) depending on a spatial distribution (Qx,ye) of a second thermal quantity (Qe) estimated beforehand from a spatial distribution (Tx,yc) of a set-point temperature (Tc) and from a spatial distribution (Dx,yr) of a first thermal quantity (Dr).
