Abstract: A metal/support catalyst for conversion of carbon dioxide to methane contains a metal including a transition metal and a support containing a perovskite-type oxide, on which the metal is supported. The metal/support catalyst for conversion of carbon dioxide to methane is capable of increasing the catalytic activity of the Sabatier reaction by promoting the formation of hydroxide ions and helping the production of formate, which is a reaction intermediate in the conversion of carbon dioxide to methane, without using a precious metal. In addition, it is capable of conducting the reaction stably for a long period of time.

Abstract: A metal-ceramic composite for a fuel cell anode is disclosed. In the metal-ceramic composite, the content of the metal is greatly reduced and the intervals between the metal particles are maintained constant, achieving improved activity and conductivity. The metal-ceramic composite includes a metal catalyst raw material and a mixed-conductive ceramic. 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.

Abstract: Disclosed is a metal separator for a solid oxide regenerative fuel cell coated with a conductive spinel oxide film. In the conductive spinel oxide film, yttrium is added to a manganese-cobalt spinel oxide to suppress growth of an insulating oxide film on the surface of the metal separator and volatilization of metal. In the conductive oxide film coated on the metal separator, yttrium is segregated at the grain boundaries of the spinel so that migration of oxygen through the grain boundaries can be suppressed. Therefore, the surface of the metal separator can be protected from exposure to the atmosphere and water vapor when the solid oxide regenerative fuel cell is operated at high temperature. In addition, poisoning of electrodes by metal volatilization from the surface of the metal separator and growth of an insulating oxide film on the surface of the metal separator can be prevented. Therefore, the stability of the solid oxide regenerative fuel cell stack can be markedly improved.
