FIELD: electrical engineering. SUBSTANCE: invention relates to gas-and-liquid chemical sources of electric energy for independent power supply systems with limited attendance. Chemical source has gas-diffused positive electrode made of carbon with hydrophobized barrier layer, metal negative electrode with catalyst selected from group including platinum, palladium, rhodium, gold, silver, nickel, and fuel-electrolyte mixture (per cent by mass: glycerine 15-40; water 30-50; potassium hydroxide 30-45). EFFECT: increased specific characteristics within temperature range from -30 up to +80 C. 2 cl, 2 dwg
