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.

System for regenerating a fuel cell and regeneration method

A method is provided for determining a spatial distribution (R) of a parameter of interest (R) representative of the electrical power production of an electrochemical cell, including steps of determining the spatial distribution (R) the parameter of interest (R) depending on a spatial distribution (Q) of a second thermal quantity (Q) estimated beforehand from a spatial distribution (T) of a set-point temperature (T) and from a spatial distribution (D) of a first thermal quantity (D).

Determination of a spatial distribution of an electrical production parameter of an electrochemical cell

A process for supplying a fuel cell with reactive species, including a stack of electrochemical cells divided into N different groups, wherein a plurality of steps of selectively supplying the N groups of cells with reactive species are carried out, following each of the supply steps, a step of purging the N groups of cells is carried out.

Process for supplying a fuel cell having alternate supply and purge phases

A method for determining a spatial distribution (Rc) of a parameter of interest (Rc) representative of a contact resistance between a bipolar plate and an adjacent electrode of an electrochemical cell, in which a spatial distribution (Rc) of the parameter of interest (Rc) is determined depending on the spatial distribution (Q) of a second thermal quantity (Q) estimated beforehand from the spatial distribution (T) of a set-point temperature (Tc) and from the spatial distribution (D) of a first thermal quantity (D).
