概要

• 論文の詳細を見る

• Fe-Cr ferritic alloys are applied for interconnects of solid oxide fuel cells (SOFCs) operated at around medium temperatures. The oxidation behavior of sheets with various thicknesses of Fe-22% Cr ferritic alloy, ZMG232L, was investigated. The oxidation rate of thin sheet was much higher than that of thick one because Cr content decreased under oxide layer of edge part of thin sheet therefore Cr oxide became unstable and Fe was mainly oxidized. Such accelerated oxidation was improved mainly by reducing Mn, additionally by increasing Cr and adding W.
