GAS-DIFFUSION ELECTRODE

摘要

FIELD: production of cathode for metal-air power sources. SUBSTANCE: gas-diffusion electrode has active and hydrophobic layers. Hydrophobic layer is made of woven graphitized fibrous materials manufactured by pyrolysis of cellulose hydrate under temperature of 2200 - 2400 C with surface density of 0.15 - 1.0 kg/mmwith threads linear density of 0.04 - 0.2 g/m. EFFECT: simplified process.
