A system for coating ceramic fibers for use in manufacturing a ceramic matric composite (CMC) article includes a frame having a plurality of frame members arranged so as to create a void therebetween. At least one of frame members includes a hollow body and at least one perforated hole defined in the hollow body. Thus, the ceramic fibers are securable at respective ends of the frame and extend across the void. The frame also includes an inlet in fluid communication with the perforated hole(s) so as to allow a coating material to flow into and through the hollow body and out of the perforated hole(s) at a location of at least a portion of one of the ceramic fibers. As such, the coating material is configured to cause the portion of one of the ceramic fibers to separate from the frame such that the portion is uniformly coated with the coating material.

A solid oxide fuel cell assembly (SOFC) and a method for making the SOFC are provided. An exemplary method includes forming a functionalized zeolite templated carbon (ZTC). The functionalized ZTC is formed by forming a CaX zeolite, depositing carbon in the CaX zeolite using a chemical vapor deposition (CVD) process to form a carbon/zeolite composite, treating the carbon/zeolite composite with a solution comprising hydrofluoric acid to form a ZTC, and treating the ZTC to add catalyst sites. The functionalized ZTC is incorporated into electrodes by forming a mixture of the functionalized ZTC with a calcined solid oxide electrolyte and calcining the mixture. The method includes forming an electrode assembly, forming the SOFC assembly, and coupling the SOFC assembly to a cooling system.

A multi-layer coating on an outer surface of a substrate includes a first layer applied directly to the outer surface of the substrate. The first layer includes diamond-like carbon (DLC) configured to mitigate metal whisker formation. A second layer is applied on a top surface of the first layer. The second layer is a conformal coating that includes a second material configured to bind to the top surface of the first layer and fill any microfractures that may form in the first layer. Optionally, a third layer is applied on a top surface of the second layer and includes DLC configured to protect the second layer from oxidation and degradation.
