Abstract
Anode supported solid oxide fuel cells (SOFCs) have been extensively investigated for their ease of fabrication, robustness, and high electrochemical performance. SOFCs offer a greater flexibility in fuel choice, such as methane, ethanol or hydrocarbon fuels, which may be supplied directly on the anode. In this study, SOFCs with an additional Ni-Fe layer on a Ni-YSZ support are fabricated with process variables and characterized for a methane fuel application. The addition of Ni-Fe onto the anode supports exhibits an increase in performance when methane fuel is supplied. SOFC with a Ni-Fe layer, sintered at 1000 degrees C and fabricated using a 20 wt% pore former, exhibits the highest value of 0.94 A cm(-2) and 0.85 A cm(-2) at 0.8 V with hydrogen and methane fuel, respectively. An impedance analysis reveals that SOFCs with an additional Ni-Fe layer has a lower charge transfer resistance than SOFCs without Ni-Fe layer. To obtain the higher fuel cell performance with methane fuel, the porosity and sintering temperature of an additional Ni-Fe layer need to be optimized.
