The high temperature strength and the thermal shock resistance of scandia-stabilized zirconia (ScSZ) electrolyte sheet and planar cell specimen of Solid Oxide Fuel Cell (SOFC) with the actual thickness could be evaluated successfully using by piston on ring (POR) and infrared radiation heating (IRH) methods respectively. The fracture strength of ScSZ electrolyte was decreased with increase of experimental temperature and scandia content. The fracture load of cell specimen that was tried to fabricate with anode and cathode-electrodes decreased as compared with electrolyte. The thermal shock strength of electrolyte specimen was changed with fracture strength and thermal expansion coefficient.
