Cubic silicon carbide (3C-SiC) synthesized with different methods was investigated as the anode material of low-temperature solid ceramic fuel cells because of high electron mobility, excellent thermal and mechanical stability, and high electrochemical reactivity towards redox-based reactions as well as low leakage current. The sample prepared via the carbothermal reduction method has multiple phases of cubic SiC (JCPDS 01-075-0254), SiO2 (01-076-0933), and quartz (00-008-0415), respectively. Further samples developed using hydrothermal and solid-state methods show the cubic structure of SiC with JCPDS No. 01-073-1708. Fourier transform spectroscopy confirms the presence of Si-C, Si-C and Si-O bonds in the synthesized material. Raman analysis shows the transverse optical line of Si-C stretching mode in all three samples at 801 cm-1. Thermal analysis reveals that the sample prepared using the solid-state method is more stable due to negligible weight loss and less decomposition during thermal heat treatment. The microstructure of materials synthesized using the solid-state method has more porosity, and therefore, better electrical conductivity of 1.1 Scm-1 is obtained compared to other samples synthesized by the hydrothermal method and carbothermal reduction method, respectively. The cell reached the maximum power density of 100 mW cm-2 with an open circuit voltage of 1.1 V at 550 degrees C. This work demonstrates an innovative synthesis method for 3C-SiC and novel material for developing highly efficient anode materials of solid ceramic fuel cells.
