Claim Text:
1. A method for depolluting and regenerating a catalytic fuel-cell electrode in a fuel cell having a fuel and operating with a fuel flow and at a current density, the reaction of the fuel of the fuel cell and capture of at least one polluting species occurring on said catalytic electrode, comprising the following steps: a decrease, at a constant current density being a first reference current density, in the fuel flow, relative to a nominal fuel flow, for a first length of time, leading to a value for a stoichiometric coefficient (StH a cut-off of the current for a length of time called the cut-off time; an increase in the fuel flow above the nominal flow, leading, once more, to a value of the stoichiometric coefficient higher than or equal to 1; and an increase in the current density until a second current density chosen by the operator is reached.
