Abstract

Ni–YSZ cermet anodes for solid oxide fuel cells were successfully prepared by high frequency induction heated sintering, producing a uniformly porous microstructure without abnormal grain growth found in the conventional sintering method. All sintering processes commenced below 1150 °C and finished within 2 min. The rupture strength and electrical conductivity of the sample sintered by high frequency induction heated sintering without addition of a pore former were over 180 MPa and about 2000 S cm− 1 at 800 °C, respectively.
