Abstract: A metal-air battery apparatus includes an inlet module and a main module each having a metal-air battery cell structure including a positive electrode and a negative electrode. The inlet module and the main module are electrically controlled and independently controlled from each other, and a channel through which a fluid such as air flows is defined between the inlet module and the main module. A temperature of the inlet module and a temperature of the main module are independently controlled by adjusting a discharge current density or by charging or a temperature adjustor.
