摘要
The cornmercialization of environmentally-friendly power production technologies as solid oxide fuel cells (SOFC) implies the cost reduction of the materials initially used in their design. The employment of a porous metallic support that significantly reduces the amount of active ceramic material is an interesting option. In this work, the processing of four different alloys (two Fe-based and two Ni-based) is evaluated for their possible use as porous metallic supports in SOFC. A binder system is proposed that, mixed with big-sized metallic powders, allows to obtain materials with the required porosity level (>= 30%). Moreover, a stage of grinding prior to compaction of mixes binder,metallic powder allows the manufacturing of dimensionally stable components during binder removal, even although their high porosity.
