Zusammenfassung: | Provided is a separator-equipped air electrode for a metal-air battery, the separator-equipped air electrode including a separator composed of a hydroxide-ion-conductive inorganic solid electrolyte being a dense ceramic material; an air electrode layer containing an air electrode catalyst and an electron-conductive material, or containing an air electrode catalyst also serving as an electron-conductive material; and an intermediate layer disposed between the separator and the air electrode layer, improving the adhesion between the separator and the air electrode layer, and exhibiting hydroxide ion conductivity. The present invention enables an air electrode provided with a dense ceramic separator to ensure the desired characteristics of the dense ceramic separator and reduces the resistance of a metal-air battery (in particular, the interfacial resistance between the air electrode layer and the separator). |
