Abstract:
An improved ceramic interconnect component for a solid oxide fuel cell having good electrical conductivity thermodynamic stability in the presence of fuel and a coefficient of thermal expansion matching closely that of zirconia electrolytes is disclosed. The interconnect is a lanthanum strontium chromate material containing minor quantities of calcia, and iron and, optionally, very minor quantities of cobalt, as dopants.
