Description
Solid oxide fuel cells have long suffered from degradation due to impurities in the fuel and complexities associated with dissimilar materials and high operating temperatures.This degradation lowers the usable cell power output and requires ancillary equipment for fuel sulfur removal and reformation.A unique microstructure for the tubular anode will be produced using a novel freeze-casting technique, which will increase the cell triple phase boundary area and result in higher power density.An infiltration of the freeze-cast anode with a newly discovered mixed metal oxide catalyst promises to significantly increase the sulfur and coking tolerance of the anode.In the proposed effort, freeze-cast SOFC tubes will be produced using varying freeze casting formulations and parameters to optimize the pore morphology and then infiltrated with the novel catalyst material.Extensive single cell and stack performance testing will be completed, and a portable 250 W SOFC generator will be designed, built, and tested using the freeze-cast tubular technology.
