PROBLEM TO BE SOLVED: To provide an air cell superior in an anti-leakage property after discharging wherein an opposing area of an air electrode to a gel zinc negative electrode is made to be increased and a utilization factor of the negative electrode is improved by a gel electrolytic solution containing no zinc powder filled up in the cylindrical cell having a cylindrical air electrode. SOLUTION: It is possible to obtain a cylindrical air cell which contains no zinc powder, which is superior in discharging and also superior in leakage after discharging because the opposing area of the air electrode to the gel zinc negative electrode is increased and the utilization factor of the negative electrode is improved by the gel electrolytic solution 23 filled beforehand into a part opposing an inner side of a metal inner cap 17 inside a separator 8 constituted and inserted inside the cylindrical air electrode 4. In addition, the cylindrical air electrode of a three-layered structure consists of a catalytic layer 1, a current collector layer 2 and a water-repellent fluororesin porous membrane layer 3, and its lower part is inserted into a resin mold 19 coated with a sealer 18 and sealed by an positive electrode can 11 being pressurized. |
