Claim Text:
1. A metal-air battery comprising: a negative electrode metal layer disposed on a first side of a negative electrode electrolyte layer; a single positive electrode layer disposed on an opposite second side of the negative electrode electrolyte layer, the positive electrode layer comprising a positive electrode material which is capable of using oxygen as an active material; and a gas diffusion layer disposed on a side of the positive electrode layer which is opposite the negative electrode electrolyte layer, wherein the negative electrode electrolyte layer is between the negative electrode metal layer and the positive electrode layer, wherein the positive electrode layer contacts a lower surface and an opposite upper surface of the gas diffusion layer, wherein one side surface of the gas diffusion layer is exposed to an outside, wherein the gas diffusion layer comprises a plurality of gas diffusion layers comprising a first gas diffusion layer and a neighboring second gas diffusion layer, wherein the negative electrode metal layer, the negative electrode electrolyte layer, and the positive electrode layer have a serpentine configuration, and wherein the positive electrode layer directly contacts a lower surface of the first gas diffusion layer and an upper surface of the second gas diffusion layer, and wherein the negative electrode metal layer, the negative electrode electrolyte layer, and the positive electrode layer are bent by 180 degrees.
