ABSTRACT:
One aspect of the invention relates to an interconnect for an SOFC wherein the interconnect is made from a cermet including partially stabilized tetragonal zirconia and a superalloy that is resistant to oxidizing and reducing conditions. Another aspect of the invention relates to an SOFC having vias for carrying fuel and an oxidant and at least one patterned feature in the anode, electrolyte, cathode and/or interconnect for laterally distributing the fuel or oxidant.
