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 method for preparing a sulfide-based solid electrolyte which is stable upon exposure to the air is provided. Specifically, a stabilization layer is formed on the surface of a sulfide-based solid electrolyte particle through treatment with a reactive gas.The sulfide-based solid electrolyte with superior air stability can be obtained because oxidation or reduction reactions with water, etc. in the air occur on the stabilization layer rather than on the sulfide-based solid electrolyte particle.

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.
Abstract translation: 公开了一种涂覆有导电尖晶石氧化物膜的固体氧化物再生燃料电池的金属隔板。 在导电性尖晶石氧化物膜中，将钇添加到锰 - 钴尖晶石氧化物中以抑制金属隔板表面上的绝缘氧化物膜的生长和金属的挥发。 在涂覆在金属隔板上的导电氧化膜中，钇在尖晶石的晶界处分离，从而可以抑制氧通过晶界的迁移。 因此，当固体氧化物再生燃料电池在高温下运行时，可以保护金属隔板的表面不暴露于大气和水蒸汽。 此外，可以防止从金属隔板的表面金属挥发引起的电极中毒和金属隔板表面上的绝缘氧化膜的生长。 因此，可以显着提高固体氧化物再生燃料电池堆的稳定性。
