摘要： A method for severing a solid-oxide fuel cell bi-layer element including a structural anode and an electrolyte layer, comprising the steps of orienting the bi-layer element such that the surface thereof is accessible to laser treatment; impinging a laser beam on the electrolyte surface; moving the impinged laser beam past the surface along a path in a plane corresponding to the desired severed edge to form a groove in the element extending partially through the element to a predetermined depth; and applying a bending moment across the groove to cause the element to break into first and second portions. The groove depth is preferably about 15% of the total thickness of the element.

摘要： In one embodiment, the method of producing a ceramic assembly includes: disposing an electrode precursor on an electrolyte precursor having an electrolyte sintering shrinkage, disposing a stabilizer precursor having a stabilizer sintering shrinkage on the electrode precursor on a side opposite the electrolyte precursor to form a precursor assembly, and sintering the precursor assembly to form the ceramic assembly comprising a stabilizer layer, electrode, and electrolyte. The difference between the electrolyte sintering shrinkage and the stabilizer sintering shrinkage is less than or equal to ±1% and a surface of the ceramic assembly has less than or equal to about 5.0 degrees camber, as measured from the horizontal plane.

摘要： A catalyst for preferentially reducing carbon monoxide in a hydrogen stream. The catalyst is formed from a chemical composition including a hexaaluminate, a metal hydroxide and a precious metal. The composition may be disposed on a support or may be extruded or cast into or onto a support. Incorporation of hexaaluminates allows inclusion of metal hydroxides that flux the active precious metal surface at higher temperatures than can aluminum oxide-based catalytic compositions, thereby enhancing resistance of the catalyst and monolithic support and increasing the durability and thermal range of the PROX catalyst. An additional advantage is that lesser amounts of precious metal oxides need be deposited onto the hexaaluminate, while retaining activity similar to aluminum oxide compositions.
摘要翻译： 用于优先还原氢气流中的一氧化碳的催化剂。 催化剂由包含六铝酸盐，金属氢氧化物和贵金属的化学组合物形成。 组合物可以设置在支撑体上，或者可以挤压或浇注到载体上或载体上。 六铝酸盐的加入允许包含在比氧化铝基催化剂组合物更高的温度下助熔活性贵金属表面的金属氢氧化物，从而增强催化剂和整体式载体的耐受性，并增加PROX催化剂的耐久性和热范围。 另外的优点是少量的贵金属氧化物需要沉积到六铝酸盐上，同时保持与氧化铝组合物类似的活性。
