High fuel utilization conditions result in reduced electrochemical performance in SOFCs due to an increase in anodic polarization. One approach to solve this problem is to increase the anodic TPB length by deposition of sub-micron nickel particles in cells with Ni/YSZ cermet anodes. The stability of these nano-sized catalysts is also critical. This paper reports the results of nickel infiltration on the performance of anode-supported SOFC over a wide range of hydrogen and water vapor partial pressures at intermediate temperatures. Various techniques to keep the nano-sized catalysts stable will also be discussed. I-V and EIS results will also be presented and the performance of the cells will be connected to the anode microstructure.
