PURPOSE: A performance measurement apparatus of an air-zinc battery is provided to be able to perform the accurate performance measurement of a cathode even though the alkaline solution is evaporated during the performance measurement by the cathode being positioned in the lower part. CONSTITUTION: A performance measurement method of an air-zinc battery comprises an alkaline solution container (110) in a cylindrical form accommodating the alkaline solution including a zinc electrode (130) inside; a cathode (120) positioned inside of a cathode case combined to the lower part of the alkaline solution container; and an electric potential measurement part (150) measuring the electric potential difference of the zinc electrode and cathode. The alkaline solution container is a cylindrical shape open in the lower part and is formed with an alkaline solution supplement hole (112) supplementing the alkaline solution on the upper end. The alkaline solution is potassium hydroxide solution (111). |
