INTERCONNECTOR FOR LOW-TEMPERATURE SOLID OXIDE FUEL CELL Russian patent published in 2019 - IPC H01M8/21 H01M8/124 H01M8/228 C23C14/16 C23C16/40 

FIELD: chemistry.

SUBSTANCE: invention relates to an interconnector for a low-temperature solid oxide fuel cell, a method for its production and a battery of fuel cells comprising at least one interconnector which can be used to produce electric power. Said interconnector comprises a bearing base of stainless steel, comprising a first surface and a second surface, a layer containing chromium oxide on a first surface of the base, wherein the chromium oxide layer has thickness of 350 nm to 600 nm, a metal oxide coating on the chromium oxide layer and an aluminium oxide layer on the second surface of the support base. Interconnector manufacturing method includes application of metal oxide metal oxide coating on first surface of bearing base from stainless steel to produce bearing base with coating and heating bearing base with coating to temperature of 800 °C to 920 °C, to obtain a layer containing chromium oxide with thickness of 350 nm to 600 nm between the first surface and the metal oxide coating and providing a layer of aluminium oxide on the second surface of the support base.

EFFECT: obtaining an interconnector which is protected from corrosion while maintaining structural integrity during the life of the fuel cell battery.
