摘要： A solid oxide fuel cell includes an anode, a cathode, an electrolyte including zirconia between the anode and the cathode, and at least one current collector on a surface of the anode opposite the electrolyte and/or a surface of the cathode opposite the electrolyte. The at least one current collector may include a material of Mn+1AXn composition, wherein M is an early transition metal, A is a Group IIIA element or a Group IVA element, X is carbon (C) or nitrogen (N), and n is an integer from 1 to 3. Related methods and systems are also disclosed.

摘要： A method of additive manufacturing may include disposing a layer of a powder material on a surface of a build platform of an additive manufacturing apparatus. The method may also include placing a compaction platform comprising one or more transducers in contact with an upper surface of the layer of the powder material. The method may additionally include activating at least one transducer of one or more transducers of the compaction platform of the compactor to densify a portion of the layer of the powder material below the at least one transducer while at least the weight of the compaction platform applies a normal force to the layer of the powder material. Related systems for densifying additively manufactured components are also described.
