METHOD FOR MANUFACTURE OF BATTERY OF TUBULAR SOLID OXIDE FUEL CELLS, AND BATTERY MANUFACTURED BY CLAIMED METHOD Russian patent published in 2022 - IPC H01M8/12 H01M8/243 H01M4/88 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to high-temperature solid oxide fuel cells (hereinafter – SOFC) of tubular geometry with a carrying anode electrode and their manufacturing method. Individual tubular SOFC are placed in through holes of a support plate, solder is applied to zones of placement of tubular SOFC in holes of the support plate, after which soldering is performed, while solder is made of electroconductive material with a melting temperature higher than an operating temperature of SOFC, and a thermal expansion coefficient (hereinafter – TEC) closer to TEC of materials of the support plate and SOFC electrodes. The surface of SOFC electrode (an anode electrode or a cathode electrode, as well as the surface of electrolyte near the anode electrode) in the area of soldering of each individual SOFC placed in the hole of the support plate is precoated with a layer of electroconductive material resistant to the operating temperature of SOFC. The layer of electroconductive material is a layer of, for example, nickel, platinum, or titanium hydride.

EFFECT: increase in the reliability of microtubular SOFC batteries; increase in the manufacturability of a method, and reduction in the duration of a process of the assembly of SOFC battery due to the combination of electrical switching and sealing into one operation, using high-temperature metal solders and carrying out a soldering operation.
