    摘要: A thermal barrier coating (TBC) (26) for a component (10) intended for use in a hostile thermal environment. The TBC (26) has an interior region (32) and an outer surface region (34) on and contacting the interior region (32). Both regions (32,34) are formed of a ceramic material, with the interior region (32) having a lower thermal conductivity than zirconia partially stabilized by about seven weight percent yttria. The interior region (32) constitutes more than half of the thickness of the TBC (26), and the outer surface region (34) constitutes less than half of the thickness of the TBC (26). The TBC (26) has a columnar microstructure whereby the interior region (32) and the outer surface region (34) comprise columns (30) of their ceramic materials. The outer surface region (34) is more erosion and impact resistant than the interior region (32) at least in part as a result of the columns (30) thereof being more closely spaced than the columns (30) of the interior region (32).

    摘要: A fuel cell stack (10) includes at least one fuel cell unit (20) and a number of interconnects (22) defining at least two openings (24) and including at least one flow field (34) for flowing a reagent. Each opening defines a respective fuel manifold (25), including at least one each of intake and exhaust fuel manifolds (251, 252). The fuel cell unit includes an anode (26), a cathode (28), and an electrolyte (27) disposed therebetween. The anode is adjacent to and in both electrical connection and fluid communication with one of the interconnects, which has a flow field (34) that guides a fuel flow between the intake and exhaust fuel manifolds. The cathode is adjacent to and in both electrical connection and fluid communication with another interconnect with a flow field (34) that guides an oxidant flow. The fuel cell stack includes a perimeter isolation seal (44) and at least two interior isolation seals (45) for sealing the electrolyte to the respective interconnects.

    摘要: A system for damping vibrations in a turbine includes a first rotating blade (50) having a first ceramic airfoil (62), a first ceramic platform (72) connected to the first ceramic airfoil (62), and a first root (74) connected to the first ceramic platform (72). A second rotating blade (50) adjacent to the first rotating blade (50) includes a second ceramic airfoil (62), a second ceramic platform (72) connected to the second ceramic airfoil (62), and a second root (74) connected to the second ceramic platform (72). A non-metallic platform damper (78) has a first position in simultaneous contact with the first and second ceramic platforms (72).
