Abstract
An object of the present invention is to provide a fuel electrode doubling as a support of a solid oxide fuel cell, whose conductivity and strength hardly lower through repetitive exposure to a reducing atmosphere/oxidazing atmosphere. Specifically, a fuel electrode 30 doubling as a solid oxide fuel cell according to the present invention includes: a three-dimensional network structure 10 formed by oxide coarse particles 12 connected to one another via an aggregate 14; electrode particles 20 dispersed in gaps 16 of the three-dimensional network structure and having a function as an electrode catalyst; and an aggregate 22 of second oxide fine particles for connecting the electrode particles 20 to a surface in the gap of the three-dimensional network structure, wherein the oxide coarse particles 12 are connected to one another without the electrode particles 20.
