Abstract: A solid state sintered material is described that includes a mixed oxide of lanthanum, strontium, cobalt, iron and oxygen, and CaCO3 inclusions. The solid state sintered material can also include calcium oxide, which can form from thermal composition of calcium carbonate. The solid state sintered material can also include a pore-forming particulate material such as carbon black and/or a doped ceramic metal oxide ionic conductor such as Sm-doped ceria uniformly dispersed in the solid state sintered material. The solid state sintered material can be formed from a two-step process in which a portion of the CaCO3 is mixed with the mixed oxide materials and heated to form porous agglomerates, and the remaining CaCO3 is added during the formation of a sintering paste. The solid state sintered material described herein can be used as a cathode material for solid oxide fuel cell.

Abstract translation: 描述了包括镧，锶，钴，铁和氧的混合氧化物和CaCO 3夹杂物的固态烧结材料。 固态烧结材料还可以包括可以由碳酸钙的热组成形成的氧化钙。 固态烧结材料还可以包括均匀分散在固态烧结材料中的成孔颗粒材料如炭黑和/或掺杂的陶瓷金属氧化物离子导体，例如Sm掺杂的二氧化铈。 固态烧结材料可以由其中一部分CaCO 3与混合氧化物材料混合并加热形成多孔团聚体的两步法形成，并且在形成烧结糊时添加剩余的CaCO 3。 本文所述的固态烧结材料可用作固体氧化物燃料电池的阴极材料。

Abstract: A fuel cell system is provided with a fuel cell stack assembly which includes a plurality of fuel cells which convert chemical energy from a fuel into electricity through a chemical reaction with an oxidizing agent, the plurality of fuel cells being stacked together in electrical series; a base member upon which the plurality of fuel cells are stacked such that the base member is in electrical communication with the plurality of fuel cells; an attachment member fixed to the base member, the attachment member being maintained at electrical ground; and a dielectric barrier which electrically isolates the base member from the attachment member.
