Powdered metal oxide mother particles, powdered metal oxide child particles, method for producing powdered metal oxide particles, powdered composite particles, and electrode for solid oxide fuel cell

摘要

Powdered metal oxide mother particles (child particles) used for a solid oxide fuel cell electrode, which have depressions or pores. A powdered metal oxide having a dispersion preparation step for preparing a dispersion containing a metal salt and a pore forming agent, and a spray pyrolysis step of spraying the dispersion onto a heating furnace to obtain a powdered metal oxide Particle production method. A powdered composite particle produced using the powdered metal oxide mother particle (child particle), and an electrode for a solid oxide fuel cell. According to the present invention, powdered metal oxide particles used for a solid oxide fuel cell electrode, a metal oxide particle having a large specific surface area, a method for producing the metal oxide particle, and a specific surface area Large composite particles and solid oxide fuel cell electrodes can be provided.
