METHOD FOR FABRICATING ELECTROLYTE LAYER OF DIRECT CARBON FUEL CELL USING VACUUM SLURRY COATING METHOD AND METHOD FOR FABRICATING DIRECT CARBON FUEL CELL THEREWITH

摘要

The present invention relates to a method for fabricating an electrolyte layer of a direct carbon fuel cell using a vacuum slurry coating method and a method for fabricating a direct carbon fuel cell therewith. The method for fabricating an electrolyte layer of a direct carbon fuel cell using a vacuum slurry coating method according to the present invention comprises the steps of: producing slurry by mixing electrolyte powder, a dispersant, a binder and a solvent (S1); dispersing the electrolyte powder by grinding the slurry with a ball mill and conducting ultrasonic treatment (S2); and conducting thermal treatment after coating the slurry on a cylindrical anode support by using a vacuum slurry coating method (S3). According to the method for fabricating an electrolyte layer of a direct carbon fuel cell and a method for fabricating a direct carbon fuel cell therewith, the performance and long-term stability of a direct carbon fuel cell can be improved by forming the electrolyte layer on the anode support to be a thin and compact coating layer.
