摘要

Chromia-forming alloys are one of the best candidates for the interconnecting materials in solid oxide fuel cells (SOFCs). However, low electronic conductivity and volatility of the chromia scale need to be solved to improve performance of planar-type SOFCs. In the field of high temperature oxidation of metals, it is well known that the additions of reactive elements into alloys improve oxidation resistance of alloys at high temperatures. In this paper, La-coating by the vacuum deposition method is applied, and the effects of La-coating on oxidation of the chromia-forming alloy in SOFC operating atmospheres are examined.
