摘要： The current invention includes an additive manufactured electrode that may be used for a flow battery system. In some embodiments, the electrode may include a composite material and/or at least one flow channel to direct, or at least influence, flow of electrolyte. The flow channel can be formed onto a surface and/or within a body of the electrode, and may be used to generate fluid pathways that cause the electrolyte to flow in a certain manner. The composite material may include a rigid core and a flexible compressible outer layer that may improve reactions zones, enhance mechanical properties, and/or provide low-pressure paths for electrolyte to flow.

摘要： A method of making an interconnect for a solid oxide fuel cell stack includes providing a chromium alloy interconnect and providing a nickel mesh in contact with a fuel side of the interconnect. Formation of a chromium oxide layer is reduced or avoided in locations between the nickel mesh and the fuel side of the interconnect. A Cr—Ni alloy or a Cr—Fe—Ni alloy is located at least in the fuel side of the interconnect under the nickel mesh.
