Abstract

Official abstract text for this publication.

The present invention is an air battery B 1 in which a cathode assembly 40, including a porous cathode layer 41, and an anode assembly 30 are disposed on mutually opposite sides of an electrolytic solution layer β. It includes an electrically conductive cathode support plate 42 that supports the porous cathode layer 41 and includes a ventilation area, wherein the porous cathode layer 41 covers the ventilation area and further extends to a non-ventilation area outside the ventilation area, and includes a dense portion 41 a at an outer edge part facing the non-ventilation area.

First claim

Opening claim text (preview).

1 . An air battery, comprising: a cathode assembly comprising a porous cathode layer and an anode assembly that are disposed on mutually opposite sides of an electrolytic solution layer; and an electrically conductive cathode support plate that supports the porous cathode layer and comprises a ventilation area, wherein the porous cathode layer covers the ventilation area and further extends to a non-ventilation area outside the ventilation area, and comprises a dense portion in an outer edge part facing the non-ventilation area. 2 . An air battery, comprising: a cathode assembly including a porous cathode layer and an anode assembly that are disposed on mutually opposite sides of an electrolytic solution layer; and an electrically conductive cathode support plate that supports the porous cathode layer and comprises a ventilation area, wherein the porous cathode layer covers the ventilation area and further extends to a non-ventilation area outside the ventilation area, and a non-water permeable adhesive layer is formed on an outer edge part of the porous cathode layer facing the non-ventilation area. 3 . The air battery according to claim 2 , wherein the cathode assembly is fixed on the electrically conductive cathode support plate by means of a non-water permeable adhesive. 4 . An air battery, comprising: a cathode assembly including a porous cathode layer and an anode assembly that are disposed on mutually opposite sides of an electrolytic solution layer, wherein the porous cathode layer covers a ventilation area and further extends to an outer edge area outside the ventilation area, and the air battery further comprises an electrically insulative cathode protection member that covers and protects the cathode assembly. 5 . The air battery according to claim 1 , wherein the cathode protection member is bonded to a cathode support plate by means of a non-water permeable adhesive. 6 . The air battery according to claim 2 , wherein the porous cathode layer is constituted of a water-repellent porous layer. 7 . The air battery according to claim 1 , wherein the porous cathode layer is at least partly embedded in the ventilation area. 8 . An air battery stack, comprising a plurality of the air battery according to claim 1 that are stacked up. 9 . The air battery according to claim 6 , wherein the porous cathode layer is at least partly embedded in the ventilation area. 10 . The air battery according to claim 1 , wherein the porous cathode layer is constituted of a water-repellent porous layer. 11 . The air battery according to claim 2 , wherein the porous cathode layer is at least partly embedded in the ventilation area. 12 . An air battery stack, comprising a plurality of the air battery according to claim 2 that are stacked up.
