Synthesis and electrical properties of scheelite Ca1−xSmxMoO4+δ solid electrolyte ceramics

▶ SmxCa1−xMoO4+δ solid electrolyte with a tetragonal scheelite structure. ▶ SmxCa1−xMoO4+δ electrolyte is one of the best candidates to replace the YSZ electrolyte for SOFCs because of their high oxide ion conduction. ▶ The sintering temperature is greatly lower than traditional YSZ electrolyte.
