PURPOSE:To improve the long term storage stability of an air cell considerably by employing the metal phthalocyanine soluble to the water containing the sulfone group and active carbon made of coal for the air electrode. CONSTITUTION:A positive electrode can 1 also used as the positive terminal has an air supply hole 2 at the bottom while the air electrode 3 contacting with a lyophilic semi-transparent film 4 is made of active carbon made of coal which is immersed in a cobalt phthalocyanine 5% water solution containing sulfone group then the solute is adsorbed by the active carbon in the range of 5-50% concn. of the adsorbed material and dried under the temperature of 100 deg.C thereafter immersed in a teflon emulsion and dried. The electrolyte holding layer 5 for holding the caustic alkali electrolytic liquid is a liquid holdable and liquid resistant nonwoven fabric or porous member and contacts with the negative member 6. An air permeable paper 7 will contact through a porous teflon sheet 8 with the air pole 3 while the other face will contact with the positive pole can 1. The negative pole can 9 will seal the cell through a gasket 10. |
