摘要： A method for replenishing an electrolyte of a molten carbonate fuel cell stack includes: preparing an electrolyte colloidal solution containing 10% to 20% of the electrolyte and having a viscosity of 200 to 800 Pa·s; replenishing the electrolyte of the cell stack using the electrolyte colloidal solution prepared in step 1 to allow the electrolyte to adhere to an electrode and an internal channel of the cell stack; discharging excess electrolyte colloidal solution in the cell stack; and drying and discharging water or an organic solvent in the cell stack under an inert gas condition to complete replenishment of the electrolyte of the cell stack, and performing a discharge performance test.
