The manufacturing of solid oxide fuel cell (SOFC) and its main components at low temperature are very important to optimise the performance of material, cell and lower the cost. The cubic full dense yttria stabilized zirconia (YSZ) electrolyte, one of the most popular electrolyte in SOFC, is obtained by three-step sintering process at 1 200-1 300 degrees C from nano powders, which needs to be dense at 1 400-1 450 degrees C by traditional sintering process. The scandia stabilized zirconia (ScSZ) and gadolinia doped ceria (GDC) electrolytes are sintered to be full dense respectively at low temperature of 900 degrees C and 800 degrees C from 3nm powders of ScSZ and by sintering additives, which, now, are widely used in SOFC process. The low temperature process of SOFC would be benefit to put forward SOFC commercial ization in the market.
