ABSTRACT:
The fuel cell structure is constituted by a plurality of cells disposed in electrical contact with one another, each cell comprising two porous electrodes, an electrolyte filling the gap between the said electrodes, and two impermeable bipolar current collectors. The bottom and top portions of the collectors (23) are provided on both faces thereof with grooves or hollows enabling the anode face of the collectors to be supplied with fuel and the cathode face to be supplied with oxidant. Elongate ribs (39, 37, 38) constitute distribution channels (35, 36) for the gas flows, the said channels supplying channels which run over the central conductive zones (24) of the collectors substantially vertically.
