A solid oxide fuel cell (SOFC) includes a cathode electrode, a solid oxide electrolyte, and an anode electrode. The electrolyte includes yttria stabilized zirconia and scandia stabilized zirconia, such as scandia ceria stabilized zirconia.

Heterogeneous ceramic composite SOFC electrolyte

Methods for fabricating an interconnect for a fuel cell stack that include providing a protective layer over at least one surface of an interconnect formed by powder pressing pre-alloyed particles containing two or more metal elements and annealing the interconnect and the protective layer at elevated temperature to bond the protective layer to the at least one surface of the interconnect.

Method of fabricating an interconnect for a fuel cell stack

A chromium-iron interconnect includes at least one of Fe rich regions in the interconnect and carbon in the interconnect.

Composition and processing of metallic interconnects for SOFC stacks

A method of making a solid oxide fuel cell (SOFC) includes providing a solid oxide electrolyte and depositing at least one electrode on the electrolyte by PVD, such as sputtering. A method of making an interconnect for a fuel cell stack includes providing an electrically conductive interconnect, and depositing a layer on the interconnect by PVD, such as depositing a LSM barrier layer by sputtering. The SOFC and the interconnect may be located in the same fuel cell stack.

Coating process for production of fuel cell components

Methods for fabricating an interconnect for a fuel cell stack include placing a compressed metal powder interconnect on a porous support, and sintering the interconnect in the presence of a non-oxidizing gas. The method may further include placing the sintered interconnect on a porous support, and oxidizing the interconnect in the presence of flowing air, or placing the sintered interconnect on a dense, non-porous support, and oxidizing the interconnect in the presence of a gas comprising pure oxygen or an oxygen/inert gas mixture that is substantially nitrogen-free.

Fuel cell interconnect heat treatment method

Methods of heat treating at least one component of a solid oxide fuel cell (SOFC) system. The method includes heating the at least one component with a rapid thermal process, wherein the rapid thermal process heats at least a portion of the component at a rate of approximately 50&#xb0; C./sec or more.
