CERAMIC COMPOSITE FOR FUEL CELL ANODE AND METHOD FOR PREPARING THE SAME
A ceramic composite for a fuel cell anode is disclosed. A method for preparing the metal-ceramic composite for a fuel cell anode, the metal-ceramic composite including (i) metal catalyst nanoparticles and (ii) a mixed-conductive ceramic, comprising (A) co-depositing a metal catalyst raw material and a mixed-conductive ceramic by physical vapor deposition. The metal catalyst raw material is present in an amount such that the content of the metal catalyst nanoparticles in the metal-ceramic composite is significantly lower than in conventional metal-ceramic composites. The presence of a small amount of the metal catalyst nanoparticles in the metal-ceramic composite minimizes the occurrence of stress resulting from a change in the volume of the metal catalyst and provides a solution to the problem of defects, achieving improved life characteristics. Also disclosed is a method for preparing the metal-ceramic composite.
