PURPOSE:To improve long term storability by employing an air electrode where powder or granular active carbon and metallic chelete compound are coexisted and gel elctrolyte having viscosity. CONSTITUTION:Active carbon is immersed sufficiently in a solution where 2g of cobalt phthalocyanine is disolved into 300g of quinoline through gas absorption method while using powder or granular active carbon having superficial area of approx. 800m<2>/g then it is depressure dried under 100 deg.C in liquid state to evaporate quinolin and to deposite cobalt phtalocyanine into active carbon then it is taken up and dried. Said process is repeated several time and approx. 5 wt% of cobalt phthalocyanine is deposited for active carbon then mixed with 3 wt% of Thephlone fine powder and held between stainless net, then pressurized to make thin board and water-rejective procession of Tephlone is performed to provide air electrode 3. While caustic alkaline gel eletrolyte of 10000 centi poise viscosity is impregnated into electrolyte holding layer 6. |
