Disclosed is a pouch type metal-air battery. In the pouch type metal-air battery, when the electrolyte inside the cell comes out of the electrode assembly by applying external pressure, the electrolyte does not reach the space partitioned by the gas diffusion layer, the electrode assembly and the exterior material, due to the step caused by the projection part of the gas diffusion layer. As such, a plurality of pores in the exterior material, which corresponds to the space, may not be blocked. Therefore, since oxygen selectively permeated from the exterior material flows into the gas diffusion layer, and flows into the electrode assembly through the diffusion portion of the gas diffusion layer, the contact resistance with pressure may improve and the initial driving conditions and driving reproducibility may be secured.

A metal air battery cell has a sealed pouch defined by a metallocene film and a gas and liquid impermeable flexible layer, and an electrochemical cell contained within the pouch.
