Inventor: OH GWANG SEOK
IPC: H01M4/96
Filed: 2020-06-02
Abstract: A pouch-type metal air battery according to an embodiment of the present invention is designed so that electrolyte (400) inside a cell cannot reach a space divided into a gas diffusion layer (200), an electrode assembly (100) and an exterior material (300) owing to a step formed on a protrusion part (220) of the gas diffusion layer (200) even if the electrolyte is taken out of the electrode assembly (100) by the application of external pressure. Therefore, a plurality of pores (310) in the exterior material (300) corresponding to the space part are prevented from being encapsulation blocked, thereby introducing hydrogen, which has been selectively transmitted from the exterior material (300), into the gas diffusion layer (200), and introducing the same into the electrode assembly (100) through a diffusion part (210) of the gas diffusion layer (200). Accordingly, contact resistance depending on pressure can be improved and the initial operating conditions and operation reproducibility of the pouch-type metal air battery according to the present invention can be ensured.
