Abstract
An air battery has a cathode layer, an anode layer and an electrolyte layer interposed between the cathode and anode layers. At least one of the cathode and anode layers has a passage forming member such that, when the air battery is adjacently stacked to another air battery, the passage forming member is situated between the air battery and the adjacent air battery so as to form an air passage to cathode layer. The passage forming member has conductivity and the ability to be elastically deformed according to expansion of the electrolyte layer. It is possible by this structure to, when there occurs increase in internal resistance due to expansion of the electrolyte layer, compensate such increase in internal resistance by decrease in contact resistance, maintain the cross-sectional area of the air passage at a predetermined size and prevent decrease in the output of the air battery.
