Abstract

Provided is an air electrode/separator assembly including a hydroxide ion conductive dense separator and an air electrode layer provided on one side of the hydroxide ion conductive dense separator. The air electrode layer includes: an internal catalyst layer provided closer to the hydroxide ion conductive dense separator and filled with a mixture containing a hydroxide ion conductive material, an electron conductive material, an organic polymer, and an air electrode catalyst (provided that the hydroxide ion conductive material may be the same material as the air electrode catalyst, and provided that the electron conductive material may be the same material as the air electrode catalyst); and an outermost catalyst layer provided away from the hydroxide ion conductive dense separator having a porosity of 60% or more, composed of a porous current collector and a layered double hydroxide (LDH) covering a surface thereof.
