LEAK-PROOF NICKEL-HYDROGEN CELL Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: leak-proof nickel-hydrogen cell has positive nickel oxide electrodes electrically coupled to negative hydrogen electrodes by means of multilayer asbestos paper, hydrogen electrodes made in the form of metal-ceramic base with porosity 20-30% and thickness 40-120 μkm with hydrophobized platinum-palladium active layer having thickness 1.0-10.9 μkm applied to it and fluoroplastic layer having thickness 0.25-5.0 μkm applied to surface of active layer. Active layer is manufactured in the form of alternating hydrophobized sections and hydrophilic channels with outlet to surface of fluoroplastic layer. Metal-ceramic base of hydrogen electrode has direct contact with asbestos paper playing role of electricity carrier. EFFECT: improved electrical characteristics. 3 cl, 5 dwg
