The present invention relates to a solid oxide fuel cell for internal reforming of hydrocarbons and carbon dioxide, in particular, to a solid oxide fuel cell in which one side of solid oxide electrolyte (YSZ) is attached to an air electrode (La0.8Sr0.2MnO3) and its other side is attached to a catalyst electrode of Ni-YSZ type or perovskite type metal oxide. The electrochemical conversion system using the solid oxide fuel cell permits the occurrence of internal reforming of hydrocarbons and carbon dioxide concomitantly with the coproduction of a syngas and electricity, and overcomes the shortcomings associated with the catalytic deactivation due to carbon deposition and the high-energy consumption.

摘要:
The present invention relates to a Ni-based catalyst for preparing syngas and a tri-reforming reaction of methane using the catalyst, particularly to a Ni-based catalyst, where an active ingredient (a nickel) is impregnated in a zirconia support and the zirconia is doped with a yttrium and a metal selected among a lanthanum and an alkaline earth metal to distort the crystal lattice of the zirconia, to facilitate the transfer of oxygen ion and to increase the storage and supply of oxygen, thus inhibiting the carbon deposition on the active nickel metal and maintaining the activity of the catalyst. Particularly, if the catalyst herein is used for the tri-reforming reaction of methane where a mixture of carbon dioxide, oxygen and steam is used as an oxidant, the molar ratio of hydrogen and carbon monoxide (H2/CO) in the syngas may be selectively controlled.
