PURPOSE:To obtain an air cell which has a high voltage and a large capacity by using an electrolyte consisting of an aqueous ammonium chloride solution. CONSTITUTION:A positive lid 1 also serving as a positive terminal is in electrical contact with a porous carbonic bar 10, and has an air supplying hole 2. An air electrode 3, which is in contact with a lyophilic barrier 4, consists of cobalt phthalocyanine, active carbon and a water-repellent fluorine resin. A pasty electrolyte 5 prepared by kneading starch into 20wt% ammonium chloride solution used as an electrolyte is in contact with a negative electrode 6 made of a zinc can. In addition, a negative can 7 is sealed, with a gasket 8 interposed between the positive lid 1 and the negative can 7, by curving the opening of the lid 1 so as to seal the battery. A sealing member 9, which is made of a polyvinylchloride sheet and seals the air supply hole 2, is a pressure-sensitive tacky agent. Since metal phthalocyanine is combined with active carbon in this invention, the electrolyte 5 has a high reducing acitivity. Consequently, both the operational discharge voltage and the discharge capacity of the battery are increased. |
