PURPOSE:To increase the storage performance and discharge performance of a battery by placing a polyorganophosphazene film between the air intake side of a gas diffusion electrode and a battery container. CONSTITUTION:A polyorganophosphazene film 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. As the supporter of the film 11, an alkali-resistant mioroporous film mainly comprising either one of polyolefin, fluororesin, and polysulfone is used. This makes oxygen permeability suitable for a battery and the penetration of water vapor and carbon dioxide is effectively blocked. The storage performance and discharge performance are increased. |
