A study on fabrication and performance of component materials for SOFC

For the purpose of reducing production costs, we have fabricated a unit cell for SOFC by the doctor blade and screen printing methods. A planar solid oxide fuel cell with an effective electrode area of about 7 cm/sup 2/ was fabricated and run for 510 h to investigate cell performance. The current density at a voltage of 0.7 V was 850 mA/cm/sup 2/.
