PURPOSE:To enhance storage properties and performance for a long use of a battery equipped with gas diffusing electrodes using oxygen as active material. CONSTITUTION:Mixture of fluorine contained resin soluble to solvent and metallic oxide powder is applied to a porous film to obtain an oxygen permeable composite film 11 which restrains vapor from being permeated and selectively takes in oxygen. By this constitution, satisfactory discharge performance required by a discharge condition for a range of low load to high load, can be obtained. And when graphite powder is made spherical in shape, scattering of film characteristics for the composite film can be made less. |
