An air electrode for a metal-air battery is disclosed. Said air electrode comprises a separator and an air-electrode layer provided on top of said separator. The separator comprises a hydroxide-ion-conducting inorganic solid electrolyte consisting of a dense ceramic. The air-electrode layer either comprises a hydroxide-ion-conducting material, an air-electrode catalyst, and an electron-conducting material or comprises a hydroxide-ion-conducting material and an air-electrode catalyst that also functions as an electron-conducting material. This invention makes it possible to significantly reduce the reaction resistance of an air electrode using a dense-ceramic separator in a metal-air battery while securing desired characteristics from said dense-ceramic separator. |
