摘要： The invention relates to the field of electrical engineering and can be used in the production of electrodes for alkaline fuel cells. An object of the invention is to increase the electrode service life. According to the invention, an electrode of an alkaline fuel cell comprises an insulating frame having ports for feeding and discharging reagents, a mesh current collector embedded in the frame and having lead-outs extending beyond the frame, an active and a barrier layers sequentially applied onto the mesh current collector, wherein sites of the embedment of the current collector and the lead-outs in the insulating frame and a periphery of the current collector along an inner edge of the insulating frame are provided with a sealing layer which can be made of an electrolyte non-wettable substance, e.g. with a sealing layer made of fluoroplastic. The invention also provides a method for producing an electrode of an alkaline fuel cell, which method includes producing a mesh current collector having lead-outs, sequentially applying an active and a barrier layers onto the mesh current collector, embedding the current collector having the lead-outs into the insulating frame, wherein, before the application of the active and barrier layers onto the current collector, edges of the current collector and the lead-outs in sites of the embedment into the insulating frame are impregnated with a lacquer solution and, after the collector has been embedded into the insulating frame, a periphery of the collector along an inner edge of the insulating frame is impregnated with the lacquer solution. A solvent wetting the mesh current collector is used as a solvent for the lacquer, and a substance which forms a continuous, electrolyte non-wettable film after the solvent evaporation is used as the lacquer.

摘要： The invention relates to the field of alcohol-air fuel cells (FC) designed for use in portable radio-electronic equipment, such as cellular phones, notebooks, etc. In accordance with the invention a fuel cell FC comprises a housing with arranged therein a liquid catalytically active anode, an air catalytically active hydrophobic gas-diffusion cathode, a liquid alcohol-alkaline mixture filling the interior cavity of the housing and separating the anode and cathode, wherein the hydrophobic surface of the cathode faces air. The surface of the cathode facing the alcohol-alkaline mixture is coated with a layer of a polymer, for example polybenzimidazole, having conduction in respect to OH- ions. A non-platinum catalyst on the base of metals Fe, Ni, Co, Ru, that is tolerant in respect to alcohol, is used as the cathode catalyst. A 4M KOH + 4M alcohol mixture is used as the alcohol-alkaline mixture, and methanol, ethanol, propanol, butanol, ethylene glycol or glycerine is used as the alcohol in the alcohol-alkaline mixture. An Ni/Ru catalyst on a high surface area carbon carrier may be used as the anode catalyst, wherein Ni/Ru is present in the anode catalyst in the form of nanoparticles. An Ni/Ru catalyst obtained by the method of thermochemical synthesis on carbon black, electrodeposition, a chemical method, mechanical mixing may be used as the anode catalyst. Silver or pyropolymers of N4-complexes on a carbon carrier may be used as the cathode catalyst. The cathode catalyst may be mixed with polybenzimidazole.
