    Abstract: The present invention relates to an electrolytic mixture for molten carbonate fuel cells (MCFCs). The carrier solution is constituted by one or more organic solvents and water, with an organic solvent percentage comprised of between 5% and 80%. The electrolyte consists of a mixture of Li2CO3 and LiKCO3 in such stoichiometric ratios as to give the Li2CO3/K2CO3 62/38 eutectic mixture. The compound LiKCO3 has a solubility in water, like lithium carbonate, less than that of the potassium carbonate, which is normally found in MCFC electrolytic mixtures. This allows the resolution of the problem of electrolyte loss during the operation of the cell, due to the solubilisation of the same in water.

    Abstract: A method and apparatus for continuous fabrication of homogeneous thin flake or powder electrolyte material from inorganic salt, metallic or similar materials or from mixtures of such materials for use in Carbonate Fuel Cell (“CFC”) power plants. Electrolyte precursor powders are fed to a continuous blender type mixer using precision metering equipment that controls material feed rates. The homogenous mixture of blended powders is then fed into a high temperature melting tank in which the mixture is melted, forming the desired molten eutectic composition. The liquid eutectic melt drips from the melting tank through ceramic or metallic nozzles and splat-cools on a rotating, water-cooled metal cylinder to produce uniform size, thin flake material. The thin flake electrolyte material can be used as-is, or it may be further processed using continuous grinding and powder fabrication equipment.

    Abstract: A system and a method for suppressing the build up of metal carbonates in the electrolyte, using a porous cell separator is used to allow the use of different electrolyte compositions around the anode (anolyte) and the cathode (catholyte). This cell configuration enables the oxygen cathode to operate in a molten hydroxide electrolyte, and the carbon anode to operate in mixed carbonate-hydroxide melt, so that most of the advantages of using a molten hydroxide electrolyte will be retained.

    Abstract: A method and apparatus for continuous fabrication of homogeneous thin flake or powder electrolyte material from inorganic salt, metallic or similar materials or from mixtures of such materials for use in Carbonate Fuel Cell (nullCFCnull) power plants. Electrolyte precursor powders are fed to a continuous blender type mixer using precision metering equipment that controls material feed rates. The homogenous mixture of blended powders is then fed into a high temperature melting tank in which the mixture is melted, forming the desired molten eutectic composition. The liquid eutectic melt drips from the melting tank through ceramic or metallic nozzles and splat-cools on a rotating, water-cooled metal cylinder to produce uniform size, thin flake material. The thin flake electrolyte material can be used as-is, or it may be further processed using continuous grinding and powder fabrication equipment.
