In some examples, a fuel cell comprising a first electrochemical cell including a first anode and a first cathode; a second electrochemical cell including a second anode and a second cathode; and an interconnect configured to conduct a flow of electrons from the first anode to the second cathode, wherein the interconnect comprises a first portion and a second portion, wherein the first portion is closer to the anode than the second portion, and the second portion is closer to the cathode than the first portion, wherein the first portion comprises one or more of doped ceria, doped lanthanum chromite, and doped yttrium chromite, and wherein the second portion comprises one or more of a Co&#x2014;Mn spinel and a ABOperovskite.

Fuel cell system including multilayer interconnect

In some embodiments, a solid oxide fuel cell comprising an anode, an electrolyte, cathode barrier layer, a nickelate composite cathode separated from the electrolyte by the cathode barrier layer, and a cathode current collector layer is provided. The nickelate composite cathode includes a nickelate compound and second oxide material, which may be an ion conductor. The composite may further comprise a third oxide material. The composite may have the general formula (LnM1M2)(NiN)O-ABO&#x2014;CDCeO, wherein A and B may be rare earth metals excluding ceria.
