METHOD FOR REMOVING DEFECT OF SOLID OXIDE FUEL CELL ELECTROLYTIC

摘要

PURPOSE: A defect removal method of solid oxide fuel-cell electrolytes is provided to improve product generation yield of the fuel cells and to prevent accidents due to defects of the electrolytes. CONSTITUTION: A defect removal method of solid oxide fuel-cell electrolytes comprises the following steps: a step of preparing a cell equipped with electrolyte(120) which has an fuel anode(110), an air electrode(130) and deformity(121); a step of providing gaseous reactive material to different sides of the electrolytes; a step of forming electrolyte material by reacting the reactant of the gaseous material with a contact surface of the electrolyte deformity; and a step of finishing the reaction by removing the defect using the electrolytes.
