ABSTRACT:
The fuel cell structure is constituted by a plurality of cells disposed in electrical contact with one another, each cell comprising first and second porous electrodes (1,2), an electrolyte filling the gap between the said electrodes and two impermeable bipolar current collectors. The electrodes are pressed against opposite faces of a frame (3) having a central orifice (4). One face (10) of the frame includes first and second grooves (11) for conveying electrolyte from an inlet orifice (8A) to a distributing manifold (12) which is in communication with the electrolyte chamber, and for conveying electrolyte away from the electrolyte chamber to an exit orifice (8B). The electrolyte distribution network on the frame (3) is sealed by a thin film (15) which extends over said network and which is fixed to the frame, that one of the electrodes (1) which overlaps the said film (15) being fixed thereto.
