A method, apparatus and assembly related to solid oxide fuel cell interconnects is disclosed. In its broadest embodiment, the invention contemplates a multi-layered ceramic interconnect having integrated flow fields and electrical connections. The method of making this interconnect includes judicious selection of materials, formation of appropriate apertures for the flow fields and electrical connectors, and the joining of the layers through a firing and/or sealing process.

A ceramic fiber composite structure particularly suitable for use as a hot gas cleanup ceramic fiber composite filter and method of making same from ceramic composite material has a structure which provides for increased strength and toughness in high temperature environments. The ceramic fiber composite structure or filter is made by a process in which a continuous ceramic fiber is intimately surrounded by discontinuous chopped ceramic fibers during manufacture to produce a ceramic fiber composite preform which is then bonded using various ceramic binders. The ceramic fiber composite preform is then fired to create a bond phase at the fiber contact points. Parameters such as fiber tension, spacing, and the relative proportions of the continuous ceramic fiber and chopped ceramic fibers can be varied as the continuous ceramic fiber and chopped ceramic fiber are simultaneously formed on the porous vacuum mandrel to obtain a desired distribution of the continuous ceramic fiber and the chopped ceramic fiber in the ceramic fiber composite structure or filter.

A ceramic element for a sootblower element is disclosed in which the element is manufactured by winding a ceramic fiber around a mandrel and subsequently densifying the composite using a sol-gel process. Separate elements are coupled together using a ceramic coupling member. Ceramic nozzle bodies are inserted into the elements. The sootblower tubes disclosed herein can withstand greater temperatures and more corrosive environments than currently used metallic lance tubes, thus enabling the sootblower element to be permanently installed within a boiler and eliminating the need for a retracting element type sootblower.
