Abstract:
Disclosed are methods of producing Ni/YSZ porous anode bodies for solid oxide fuel cells. According to the methods, a small amount of a nickel compound or salt is used as a pore former. Upon heating in air, the nickel compound or salt is decomposed into nickel oxide and releases gases, resulting in volume shrinkage. Therefore, Ni/YSZ porous bodies having a uniform pore size and reduction products thereof can be produced in an economical manner.

Abstract:
Disclosed is a metal oxide-yttria stabilized zirconia composite, including 25˜75 wt % of a metal oxide-3 mol % yttria stabilized zirconia composite, and 75˜25 wt % of a metal oxide-8 mol % yttria stabilized zirconia composite. A solid oxide fuel cell is also provided, which includes the metal oxide-yttria stabilized zirconia composite as an anode layer or a support layer of an anode layer.
