CYLINDRICAL AIR CELL

摘要

PURPOSE: To manufacture an air cell excellent in discharging during long shelf storage by providing a catalyst layer around a current collector to which nickel- polytetrafluoroethylene dispersion plating is applied and providing a water- repellent resin porous film with gas permeability on the outer periphery side of the catalyst layer. CONSTITUTION: A nickel plate layer 5 in which polytetrafluoroethylene particles 6 are dispersed is formed on the surface of a stainless steel collector 7. A catalyst sheet is made to press contact with around a plated collector 12 to form a catalyst layer 1 and a water-repellent fluororesin porous film layer 3 is made to press contact with outside the catalyst layer 1 to manufacture a three-layer structured cylindrical air pole. The air pole is used as a positive electrode to obtain a cylindrical air cell which prevents the creeping and leakage of an electrolyte.
