Abstract
Porous zirconia/nickel composite was prepared for the anode of solid oxide fuel cell (SOFC). Metalnickel and TZP were confirmed after sintering and deoxization for the mixture of fine nickel oxide, TZP and PMMA particles. Three types of pore size were observed, than were approximetely 5-10 μm pores formed by the vaporization of organic PMMA particles, submicron pores formed by the deoxidization of nickel oxide and 2 nm pores on the interface of particles. Porous TZP/Ni composites was fabricated into a cylindrical shape by centrifugal molding or a plate shape by CIP. Desirable air permeability was obtained by the addition of PMMA particles up to 30 vol%.
