Katode-elektrolyt-anode-enhed til fastoxid-brændselsceller og fremgangsmåde til dens fremstilling

摘要

Unit has a layer composition with a porous anode (3) formed in the form of a layer, gas-tight electrolyte (4) and a porous cathode (7), where the composition is formed on a porous metallic, plate-shaped and planar substrate (1). The layer forming the anode is separated from the metallic substrate by a ceramic intermediate layer (2), where the layer (2) has a barrier effect for chromium and iron and is electronically conductive when an oxygen partial pressure is within a preset value. Another layer made of ceramic and electronically conducting material is formed on a side of the substrate. An independent claim is also included for a method of manufacturing a cathode-electrolyte-anode unit.
