PURPOSE: A zinc-air fuel cell electrolyte discharge device is provided to facilitate a molding process by including an opening/closing block selectively discharging an electrolyte and to improve the usage efficiency of a small capacity battery. CONSTITUTION: A zinc-air fuel cell electrolyte discharge device comprises the following: a negative electrode bag(14) including a receiving space to store a zinc ball and an electrolyte; a current collector(16) collecting electrons generated by the reaction of the zinc ball and oxygen inside the electrolyte; a cover block(18) including a slit supplying a discharging path for the electrolyte by connecting the block with the exterior, for covering the negative electrode bag and the current collector; and an opening/closing block(20) installed on the cover block.
