1,211,592. Fuel cell. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM). 21 Feb., 1968 [24 Feb., 1967], No. 8511/68. Heading H1B. A fuel cell in which at least one gaseous or liquid reactant is used as an emulsion with the electrolyte includes an electrode comprising a conductive sheet of porous or meshed metal, the thickness of the sheet and the pore size or mesh separation being 0À1 to 1À0 mm. and is arranged so that the emulsion passes through the sheet from inlet passages for electrolyte and reactant on one edge to an opposite edge. The reactant and electrolyte inlet passages may join before opening into the electrode chamber. The totalled cross-sections of the inlets may be less than the total cross-sectional area of the electrode available for electrolyte. In a particular embodiment, Fig. 1, each cell of a battery comprises one side of each of a pair of double sided electrodes, 1, a pair of plastics spacer frames, 2, and a semi-permeable diaphragm, 3, the relative thicknesses being such that the electrodes and diaphragms touch. The electrolyte and both reactants are fed to the cells through conduits in the top perimeter of the battery and the spent reactant-electrolyte mixtures are removed from the bottom and returned to the electrolyte inlets at the top by pumps. |
