Iron-chromiumalloys (ferritic steels) forming a chromia oxide scale(Cr$_{2}$O$_{3}$) are promising materials as metallic interconnector of solid oxide fuel cells (SOFC). Typical operating temperatures of such fuel cells range between 600 and 800 °C. Chromia-containg oxide scales are necessary since they show sufficient electrical conductivity unlike alumina(Al$_{2}$O$_{3}$) or silica scales(SiO$_{2}$). However, one of the disadvantages of such alloys are volatile Cr(VI)species like CrO$_{3}$ and CrO$_{2}$(OH)$_{2}$. These volatile species arise under operating conditions of SOFC. The electrochemical reduction of these species forming solid Cr(III) oxides at the three phase boundary electrolyte / cathode / oxidant leads to a degradation of t...
