Abstract
Disclosed herein is a method of manufacturing electrolyte-impregnated anode and cathode for a molten carbonate fuel cell. The method is intended to manufacture electrolyte-impregnated electrodes for controlling an electrolyte present in unit cells of a molten carbonate fuel cell by adding electrolyte powder to prepare an electrolyte slurry, which is necessary for forming electrodes, molding electrodes containing an electrolyte in an in-situ state so that they meet the specifications for the unit cells of a fuel cell stack using a tape casting method, and then sintering the electrodes. The method includes preparing electrolyte slurry, nickel slurry and organic substance slurry; mixing the electrolyte slurry with the nickel slurry and the organic substance slurry to form mixed slurry; defoaming the mixed slurry; tape-casting the mixed slurry; and drying and sintering the tape-cast slurry.
