    Abstract: A topping cycle fuel cell unit includes a support plate having internal flow passages that extend to combustion outlets, a first electrode layer, an electrolyte layer, and a second electrode layer. The second electrode layer is configured to be coupled to another support plate of another fuel cell unit. The internal flow passages are configured to receive and direct air across the first electrolyte layer or the second electrolyte layer and to receive and direct fuel across another of the first electrolyte layer or the second electrolyte layer such that the first electrode layer, the electrolyte layer, and the second electrode layer create electric current. The internal flow passages are configured to direct at least some of the air and at least some of the fuel to the combustion outlets where the at least some air and the at least some fuel is combusted.

    Abstract: An approach for supporting a wax pattern during investment casting. The approach described herein forms a support structure to support the wax pattern during investment casting. The support structure has a capping structure with a geometry that can match a profile of a lower region of the wax pattern, and at least one support brace extending outward from the support capping structure. The support structure can be placed on a surface of the lower region. The support capping structure can form a defined envelope to enclose the lower region of the wax pattern. The support structure is connected to a base plate by the support brace(s). The capping structure and the support brace(s) secure the wax pattern to the base plate and distribute the load of the wax pattern to maximize strength while minimizing the risk of a discontinuity in the wax or shell that could affect the casting process.
