A fuel electrode serving as a support for a solid oxide fuel cell and a solid oxide fuel cell supporting the fuel electrode

摘要

The present invention provides a fuel electrode that also serves as a support for a solid oxide fuel cell, and the conductivity and strength are unlikely to deteriorate even when repeatedly exposed to a reducing / oxidizing atmosphere. The fuel electrode also serving as the support of the solid oxide fuel cell of the present invention is made of the first oxide particles having a 10% cumulative particle size of 5 μm to 12 μm and a 90% cumulative particle size of 84 μm to 101 μm. A porous structure, and electrode particles having electrocatalytic activity, covering 10% to 70% of the surface with second oxide particles, covering the surface in the voids of the porous structure. It is characterized by having.
