Solid oxide fuel cells (SOFCs) are recognized as environmentally friendly, highly efficient devices, and alternatives to conventional energy conversion systems. Typical material design used is the YSZ-based cell consisted of NiO-YSZ and LSM as anode and cathode, with a dense electrolyte of YSZ. When considering the use of hydrocarbon fuels, carbon deposition has been observed as major failure issue. Ce0.6Mn0.3Fe0.1O2 (CMF) has been studied recently because of the high tolerance against coke deposition and it also exhibited high catalytic activity. In this work, Cu-doped CMF powders were synthesized by glycine nitrate combustion process (GNC). The structure, microstructure, conductivity, coefficient of thermal expansion properties were investigated. Cu-doped CMF powders were utilized as anode material in Sr- and Mg-doped LaGaO3 (LSGM)-based electrolyte-supported solid oxide fuel cell for power performance test. The cell with structure of (Cu-doped CMF) | LSGM | LSCF was operated from 600 to 800 °C with humidified H2 as a fuel and ambient air as oxidant to evaluate the electrochemical properties.
