SOLID-OXIDE FUEL CELL AND ITS MANUFACTURING PROCESS Russian patent published in 2003 - IPC

FIELD: chemistry, catalysis, and electrochemistry. SUBSTANCE: solid-oxide fuel cell that may be used for catalysis of chemical reactions such as hydrocarbon oxidation reactions has sequentially arranged layers of porous electrode-cathode, porous cathode catalyst, solid electrolyte, anode catalyst, and porous electrode- anode; cathode and anode have through channels. Layers of cathode and anode catalysts are made of solid electrolyte nanostructures doped with additives affording mixed n- and/or p-type conduction and ionic conduction of cathode and anode catalyst layers. Fuel cell manufacturing process involves high-frequency magnetron evaporation of materials on substrate surface, the latter being inclined to magnetron discharge axis through angle smaller than 90 deg; in the process substrate is rotated about axis perpendicular to its surface. Prior to evaporating materials on substrate surface depressions and/or projections are made on the latter. EFFECT: reduced life degradation of fuel-cell electrodes, enhanced specific parameters of fuel cells. 9 cl, 1 dwg
