초록
SOFC (Solid Oxide Fuel Cell) Ni-YSZ anode was fabricated by the spark plasma sintering (SPS) process and its microstructure and electrical properties were investigated in this study. The spark plasma sintering process was carried out at 800~1000℃ for holding time of 5 min under 40 MPa. To fabricate Ni-YSZ anode, the SPS processed specimens were reduced at 800oC under H2 atmosphere. The reduced specimens showed relative density of 48.4~64.8% according to sintering temperature. And also, the electrical conductivity of reduced specimens after sintering at 900 and 1000℃ showed 480~600 (S/cm) values at the measuring range of 600~900℃.
