GAS-DIFFUSION ELECTRODE FOR CHEMICAL SOURCE OF ELECTRIC ENERGY Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: gas-diffusion electrode includes adhesion layer composed per cent by mass, of: activated carbon 85-98 and polyethylene with molecular mass from 10⁶ up to 6·10⁶ 2-15; hydrophobic layer incorporating ( per cent by mass): technical carbon 60-95 and polyethylene with molecular mass from 10⁶ up to 6·10⁶ 5-40. Hydrophobic layer can include per cent by mass: technical carbon 60-95; polyethylene with molecular mass from 10⁶ up to 6·10⁶ 4-30 and 1-20 per cent by mass of polyethylene with molecular mass from 10⁵ up to 10⁶. Current-tapping grid of electrode is positioned inside hydrophobic layer. EFFECT: enhanced operational efficiency. 3 cl, 1 tbl
