1,211,593. Fuel cell. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM) 26 Feb., 1968 [24 Feb., 1967 (2)], No. 9233/68. Heading H1B. A fuel cell in which at least one of the reactants is emulsified with the electrolyte includes at least one electrode formed of a conductive sheet of porous or meshed structure or a conductive sheet embossed to provide a network of protruberances the thickness of the porous or meshed sheet and the mesh or pore size or the depth and spacing of the protruberances being between 0À1 and 1À0 mm. and the emulsion being caused to flow through the pores or meshes or between the protruberances from one edge of the electrode to an opposite one. The meshed sheet may be a metallic gauze or lattice or a sheet of expanded metal. The embossed sheet may be of "egg-box" construction the protruberances being staggered with respect to the direction of flow of the emulsion. It may be made of metal or plastics material charged with amorphous carbon or graphite. The active surface may carry a catalyst. The electrode may be bipolar, emulsion contacting both surfaces. The emulsion may include a reclose system or a catalyst. A semi-permeable membrane may be applied to at least one face of the electrode. A battery of cells may comprise a stack of flat elements each having holes in it which line up to provide inlet and outlet ducts for electrolyte and channels from these ducts to each electrolyte chamber. In a particular embodiment Fig. 3, a battery comprises a stack of electrodes 1, spacers 14 and semi-permeable membranes 3 between plates 18 and 19. The stack is bolted together and reactive electrolyte emulsions are supplied and removed via nipples 21-24. |
