ABSTRACT:
A structure for a fuel cell comprising at least one cell formed by first and second electrodes separated by a an electrolyte, the cell being disposed between first and second interface elements for feeding the electrodes of the cell with reagent and for collecting the electric current it produced. Each interface element comprises a distributor element of insulating material including distribution channels at least in its face facing one of the electrodes for the purpose of diffusing a reagent, and at least one collector element of conductive material interposed between the electrode and the elements made of insulating material. The collector element presents perforations so as to enable the reagent to diffuse between the channels of the distributor element and the electrode facing it.
