FIELD: electrical engineering. SUBSTANCE: air electrode includes porous current lead-out produced from nickel spongy structure with density 0.3-0.5 g/cu. cm and dimension 0.5-0.8 mm on which active layer based on carbon and binder is applied and pressed under pressure 5000-8000 g/sq.cm. It is coated with protective hydrophobic layer produced from polytetrafluorethylene under pressure 150-300 g/sq.cm. EFFECT: prevention of electrode from lamination in process of use, improved operational characteristics. 2 cl, 3 tbl
