MODIFIED PLANAR ELEMENT (VERSIONS), BATTERY OF ELECTROCHEMICAL DEVICES ON ITS BASIS, METHOD TO MANUFACTURE ELEMENT AND FORM FOR ITS REALISATION Russian patent published in 2011 - IPC H01M8/12 

FIELD: electricity.

SUBSTANCE: according to the invention, in a modified planar element with a solid oxide hard electrolyte (1), a gas diffusion cathode (2), an anode (3) and a metal or an oxide current passage, the bearing hard electrolyte is arranged in the form of a waveform plate (4), made of waves and representing an isosceles trapezoid in section without a larger lower base, of identical height, with holes (9) at one side in the upper part of each wave to supply one of reagents, for instance, fuel, connected to each other near the base (6) to form gas gaps of the element in the form of tilted isosceles trapezoids without larger lower base with the angle at the low base α - equal to 0.1-89.9°, at the same time the waveform plate is connected to two opposite walls (7), front and back ones, perpendicular to waves and with identical height, and having holes (8), one to supply the second reagent into each space in the form of tilted isosceles trapezoids without a larger base on top, for instance, to supply air, the other opposite one to discharge spent gas, at the same time the waveform plate of the bearing hard electrolyte at the side of waves, which in section represent an isosceles trapezoid without a larger lower base is coated with one electrode, for instance, a cathode based on strontium lanthanum manganite (2), and at the side of the formed space - in the form of tilted isosceles trapezoids without a larger base on top by the second opposite electrode, for instance, a nickel-cermet anode (3).

EFFECT: increased density of package, improved mechanical properties and specific characteristics of an element.
