M/Ni-YSZ composite for fuel cell, the method of preparing the same, fuel cell using the same

摘要

PURPOSE: A metal/nickel-yttria-stabilized zirconia composite for a fuel cell, a manufacturing method thereof, and a fuel cell using thereof are provided to use the composite as a negative electrode catalyst with the carbon poisoning resistance. CONSTITUTION: A metal/nickel-yttria-stabilized zirconia composite for a fuel cell contains a nickel oxide doped with a metal and yttria-stabilized zirconia. The content of the metal is 0.0001~20wt% of for the amount of nickel. A manufacturing method of the metal/nickel-yttria-stabilized zirconia composite comprises the following steps: impregnating metal salt to the surface of the nickel oxide; adding the yttria-stabilized zirconia and mixing with alcohol for wet milling; spray-drying the wet-milled solution to form powder; and high temperature sintering the powder before reducing.
