Nanocatalyst for anode of solid oxide fuel cell and preparation method thereof

Abstract

The present disclosure relates to a nanocatalyst for an anode of a solid oxide fuel cell and a method for preparing the same. More particularly, the present disclosure relates to a nanocatalyst for an anode of a solid oxide fuel cell obtained by forming a ceramic nanocatalyst including a noble metal dispersed therein in an atomic unit and contained in an ionic state having an oxidation number other than 0 through an in situ infiltration process in the internal pores of a porous electrode, and to application of the nanocatalyst to a solid oxide fuel cell having significantly higher electrochemical characteristics as compared to the solid oxide fuel cells including the conventional nickel-based anode and oxide anode, and particularly showing excellent characteristics at an intermediate or low temperature of 600° C. or less.
