The sintering temperature effect on electrochemical properties of Ce_0.8Sm_0.05Ca_0.15O_2-δ (SCDC)-La_0.6Sr_0.4Co_0.2Fe_0.8O_3-δ (LSCF) heterostructure pellet.

ABSTRACT: Recently, semiconductor-ionic materials (SIMs) have emerged as new functional materials, which possessed high ionic conductivity with successful applications as the electrolyte in advanced low-temperature solid oxide fuel cells (LT-SOFCs). In order to reveal the ion-conducting mechanism in SIM, a typical SIM pellet consisted of semiconductor La_0.6Sr_0.4Co_0.2Fe_0.8O_3-δ (LSCF) and ionic conductor Sm and Ca Co-doped ceria Ce_0.8Sm_0.05Ca_0.15O_2-δ (SCDC) are suffered from sintering at different temperatures. It has been found that the performance of LSCF-SCDC electrolyte fuel cell decreases with the sintering temperature, the cell assembled from LSCF-SCDC pellet sintered at 600 °C exhibits a peak powe
