The catalytic activity of Ni-based anodic materials was investigated in complete solid oxide fuel cells (SOFCs) through electrochemical analysis. The study utilized button cells incorporating a yttria-stabilized zirconia (YSZ) electrolyte layer, a (La1-xSrx)y MnO3 (LSM) cathode, and a Ni0.5Co0.5–YSZ cermet anode. Anodes were produced via a wet impregnation technique, facilitating the development of composite electrodes with a homogenous phase distribution and controlled microstructure. Impedance spectroscopy was conducted to discern the contribution of each component to overall cell losses across varying temperatures and partial pressures of the reacting gases. Current–voltage characteristic curves were collected, and the effect of CH4 feeding was assessed and compared to H2. Notably, no deterioration in cell performance due to carbon formation at the anode occurred over a testing period of 100 hours. This research underscores the effectiveness and stability of Ni-based anodes in SOFCs when using hydrocarbon fuels, marking a significant step forward in the utilization of alternative fuel sources for power generation.
