Abstract
We controlled the amount of Y$_2$O$_3$additives, 8 mol% and 10 mol%, and the type of carbon pore former, activated carbon and carbon black, to improve the strength of porous NiO-YSZ anode materials for solid oxide fuel ceil. The 3-point flexural strength, porosity and electrical conductivity were evaluated. As a result, the strength of anode materials with the addition of carbon black was markedly improved. The strength of NiO-10 mol%YSZ sintered at relatively higher temperature was higher than that of NiO-8 mol%YSZ materials. The electrical conductivity of NiO-10 mol%YSZ with carbon black was evaluated as much as 10$^2$∼10$^3$S/cm at 700$^{\circ}C$∼1000$^{\circ}C$ in reducing atmosphere.
