FIELD: electrochemistry; manufacture of air-metal current supplies. SUBSTANCE: gas-diffusion plate has water-repelling layer, active layer, and current lead; water-repelling layer has following composition: 41-70 mass percent of polyethylene and carbon material containing 50-100 mass percent of graphite; active layer that has in its composition polyethylene and activated carbon is doped in addition with graphite in proportion of 20-60 mass percent of activated carbon content. Fractional composition of graphite introduced in water-repelling layer ranges between 0.5 and 100 mcm and particle size of graphite introduced in active layer may vary between 5 and 500 mcm. EFFECT: reduced alkali penetrability and enhanced electric conductivity of carbon-containing electrode layers. 5 cl, 3 ex |
