Chromium containing alloys are used in SOFC's as metallic interconnects to form chromia scale for corrosion protection. However, chromium vaporization at high temperatures produces gaseous chromium species resulting in SOFC degradation. This metho

Cathode poisoning from airborne contaminants in trace levels remains a major concern for long-term stability of high-temperature electrochemical systems. We provide a novel method to mitigate the cathode degradations using getters, which capture airborne contaminants at high temperature before entering electrochemically active stack area.
