PURPOSE:To increase the storage performance and discharge performance of a battery by placing a piece of glassine paper between the air intake side of a gas diffusion electrode and the inner surface of a battery container. CONSTITUTION:A piece of glassine paper 11 is placed between a gas diffusion electrode 1 using oxygen as the active material and a battery container 8 having an air intake hole 3. The glassine paper 11 has a basis weight of 30-100g/cm<2> and may be in contact with the gas diffusion electrode 1. A microporous film such as polytetrafluoroethylene may be placed between the glassine paper 11 and the gas diffusion electrode 1. An air diffusion porous member such as a nonwoven fabric may be placed between the glassine paper 11 and the battery container 8. Oxygen in the air is selectively permeated into a battery at a good permeable rate, and the penetration of water vapor and carbon dioxide is blocked. |
