/ / Fabrication Method of Li/Na Electrolyte Green Sheets for Molten Carbonate Fuel Cells and Pre-treatment and Operation Method of MCFC Comprising Li/Na Electrolyte

摘要

The present invention relates to an electrolyte green for a molten carbonate fuel cell (MCFC) by molding and drying a powder slurry including a Li / Na carbonate mixed powder, an ethanol solvent, a binder, a plasticizer, a dispersant, and an antifoaming agent by tape casting. It relates to a method of producing a sheet. The present invention also relates to an operating method including pretreatment of a molten carbonate fuel cell containing a Li / Na electrolyte.;According to the manufacturing method of the Li / Na electrolyte green sheet of the present invention, the use of ethanol as the solvent reduces the dissolution rate of the cathode without using a solvent harmful to the human body, reduces the loss by evaporation, and at the same time has a small coefficient of thermal expansion. A high quality Li / Na electrolyte green sheet having high ion conductivity can be produced. In addition, the pretreatment and operation of the molten carbonate fuel cell according to the operation method of the molten carbonate fuel cell containing the Li / Na electrolyte of the present invention, corrosion of the current collector plate and the separator plate made of a metal material, thereby reducing electrolyte consumption and battery performance And all the inherent advantages of the Li / Na electrolyte.
