Direct internal reforming catalyst for molten carbonate fuel cells method for preparing the same and method for improving long-term stability by wettability control on molten carbonate electrolyte for molten carbonate fuel cells

摘要

ABO ₃ A single phase of perovskite oxide is formed by substituting one or more doping elements for A or B or A and B sites of the perovskite type oxide so as to reduce the wettability with the molten carbonate liquid electrolyte. Thereby providing a homogenous catalyst. The catalyst is capable of producing a syngas having high methane conversion and high hydrogen ratio due to its high activity and high reaction activity over a long period of time while preventing poisoning due to creepage and evaporation of molten carbonate liquid electrolyte.
