HYDROGEN PERMEATION IN Fe-16Cr ALLOY IN THE ATMOSPHERE SIMULATING SOFC AT 1073 K

摘要

Iron-chromium ferritic alloy is a candidate for the interconnect of solid oxide fuel cells (SOFC). Gas tightness is one of the most important properties of the interconnect in planar-type SOFC. Hydrogen permeation in Iron-chromium alloy was measured at 1073 K. The results of this study revealed quantitatively that the oxide layer formed on alloy which mainly consists of Cr_2O_3 blocks hydrogen permeation.
