Abstract: A silicon nitride body is sintered in a silicon nitride crucible at a temperature ranging from about 1700 DEG C to 2100 DEG C. Sintering is carried out in the presence of nitrogen gas having sufficiently high pressure to prevent decomposition of the silicon nitride. The sintered body exhibits as-fired surface strength greater than 75 % of its bulk, machined-surface strength.

Abstract: A fuel cell stack is based on solid electrolytes, such as the oxygen-ion conducting solid oxide fuel cells and the proton conducting ceramic or polymer membrane fuel cells. The fuel cell has a radial, coflow planar stack with an integral, internal manifold and tubular porous elements for controlling the rate and uniformity of the radial fuel and oxidant fluid flows. Such construction minimizes the extent of sealing that may be required and provides for easy manifolding of stack arrays. In addition, the fuel cell construction has the potential for high mass and volume specific power densities and low fabrication costs.

Abstract: This invention relates to a process for the preparation of a crystalline compound having an empirical formula LaCrxA1-xO4.yH2O where A is a metal selected from the group consisting of Mg, Sr, Ca and Ba, x ranges from 0.99 to about 0.7 and y ranges from 0 to 0.15. The process comprises adding a solution of the appropriate metal salts to a solution of ammonium hydroxide thereby precipitating a hydroxide gel intermediate, which is dried and calcined in air to yield the resultant crystalline compound which has a huttonite structure. Additionally, this invention relates to a process for the preparation of a ceramic powder having the empirical formula LaCrxA1-xO3, where A is a metal selected from the group consisting of Mg, Sr, Ca and Ba, and x ranges from 0.99 to about 0.7. Finally, a ceramic composition having the empirical formula LaCrxA1-xO4.yH2O having a huttonite structure is also disclosed.

Abstract: A radial planar fuel cell stack comprises an internal manifold having a first interior cavity and a second interior cavity. A plurality of single cells having an anode layer, a cathode layer, and an electrolyte layer therebetween are disposed about the manifold. A manifold bracket operatively fixes the manifold to at least one of the single cells. The manifold bracket describes a channel in communication with at least one of the first and second interior cavities. A porous element is disposed in the channel and ensures uniform distribution of gases over 360°.

Abstract: Une poudre de chromite de lanthane réactive au frittage est préparée à partir du précurseur de chromite de lanthane LaCr1-xMxO3 (Adsorbat). La poudre est cristalline, est représentée par la formule LaCr1-xMxO3, où M représente le magnésium et le calcium et x va d'environ 0,03 à 0,3, et s'agglomère par frittage jusqu'à des densités plus élevées qu'environ 95% de la densité théorique à une température aussi basse que 1.600 °C dans des atmosphères inertes ou réductrices. L'agglomération par frittage jusqu'à une densité si élevée à des températures avoisinant 1.600 °C rend cette poudre particulièrement adaptée à l'utilisation comme matériau intercalaire pour des piles à combustible à oxyde solide.

Abstract: A sinter-reactive lanthanum chromite powder is prepared from the lanthanum chromite precursor LaCr1-xMxO3 (Adsorbate). The powder is crystalline, has the formula LaCr1-xMxO3, where M is selected from the group consisting of zinc, copper and mixtures thereof and x ranges from about 0.02 to 0.2, and sinters to densities higher than about 95 % of theoretical density at a temperature as low as 1400 °C in oxidizing atmospheres. Sintering to such high density at temperatures in the vicinity of 1400 °C makes the powder particularly suited for use as interconnect material for solid oxide fuel cells.
