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. One of the electrodes (2) is pressed against a frame (3) having a central orifice (4). One face of the said frame (3) includes grooves (11) for conveying electrolyte from an inlet orifice (8A) to a distribution manifold (12) which is in communication with the electrolyte compartment, and also for conveying electrolyte from the central compartment to an outlet orifice (8B). The electrolyte conveying network on the frame (3) is sealed by means of a second frame (55) made of insulating material and pressed over the said network. The frames are fixed together.
