Fabrication and Evaluation of Electrode Supported Planar SOFC III. Stack Performance

Abstract

A fuel-electrode-supported planar cell with an effective electrode area of 150 cm² was developed. A three-cell stack was built with ceramic gas separators with an electric resistance lower than 5 mΩ. An electric power generation test was carried out at 1000°C with hydrogen gas and air which were fed to the cells in series. The stack attained a maximum output power of 106 W at a fuel utilization of 70%.
