1. A method for supplying a fuel cell battery, comprising at least one stack of cells, with at least one reactant, wherein N groups of cells of the battery, N>1, are selectively supplied with the reactant in at least three phases,
a) a first phase in which a first group of cells of the N groups of cells is supplied but not a second group of cells of the N groups of cells, the reactant which is unconsumed being able however to flow between the two groups via at least one evacuation manifold connected to the cells of the two groups;
b) a second phase in which the second group of cells is supplied but not the first group of cells, the reactant which is unconsumed being able however to flow between the two groups via the at least one evacuation manifold; and
c) a third phase in which the two groups are first supplied simultaneously, then a purge valve of the at least one evacuation manifold is opened then closed.
