Abstract
A model of an anode supported solid oxide fuel cell prepared using the phase inversion is developed and validated by the experiment data tested at 800°C. The electrochemical properties are analyzed and compared with cells utilizing different anode support substrates. At 0.7 V, the power density of the cell employing a straight anode channel is 23%–40% higher than cells utilizing traditional anode substrates with porosities of 30% or 60%, respectively. Removing the sponge layer increased the power density to 3.1 W cm−2, just 3.3% higher than the straight channel cell. These results demonstrate that the straight channel anode improves gas transport, while removing the sponge layer has minimal impact on the cell's performance.
