Solid oxide fuel cells (SOFCs) have the ability to demonstrate high energy conversion efficiency with commercially available fuels over a wide array of power applications. In order to achieve commercial viability, the cost and durability of the technology require significant improvements. Here we report high performance of a tubular solid oxide fuel cell utilizing a freeze-casting process to form the anode support. In our full-cell demonstration, we employed a standard nickel cermet anode with a standard lanthanum strontium manganite perovskite cathode to show the effect of a novel pore structure within the supporting anode. When evaluated with 30 vol% H2 as the fuel at 800 oC, a decrease of concentration polarization was achieved by increasing the porosity which enabled a 42% increase in the electrochemical performance from 0.35 to 0.50 W/cm2. Controlling porosity within the SOFC active layers is highly desirable for improving the electrochemical performance which can both affect the overall cost and durability of the system. Here we show how freeze casting allows for fine tuning of the aligned porosity within the tubular, anode support of the SOFC with simple adjustments in the solids/water ratio in the casting slurries. Permeation measurements of the anode structures support these findings and show how future improvements can be made by further optimization of the anode interface between the bulk anode and the electrolyte.
