Abstract
The effects of the microstructural factors of the electrodes, such as the porosity and the pore size of the anode support as well as the thickness of the cathode, on the performance of an anode-supported thin film solid oxide fuel cell (TF-SOFC) are investigated. It is shown that the performance of the TF-SOFC with a 1 ㎛-thick yttria-stabilized zirconia (YSZ) electrolyte is significantly improved by employing anode supports with increased porosity and pore sizes. The maximum power density of the TF-SOFCs increases from 370 mWcm-2 to 624 mWcm-2 then to over 900 mWcm-2 at 600 ℃ with increasing gas transport at the anode support. Thicker cathodes also improve the cell performance by increasing the active reaction sites. The maximum power density of the cell increased from 624 mWcm-2 to over 830 mWcm-2 at 600 ℃ by changing the thickness of the lanthanum strontium cobaltite (LSC) cathode from 1 to 2~3 ㎛.
