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.
