Abstract

Institute of Nuclear Energy Research (INER) has been developing fabrication method for metal-supported solid oxide fuel cells (MS-SOFCs) operating in the range of 600-750oC. The planar MS-SOFC cell with 10×10 cm2 in size were fabricated by atmospheric plasma spraying. The measured powers of the MS-SOFC in cell test achieve 55, 44.6 and 28 W at 0.8 V and 750, 700 and 650oC, respectively. The power outputs of MS-SOFC single-cell stack are 54.7 and 44.3 W at 0.7 V and 750 and 700oC, respectively. The durability tests of the MS-SOFC cell had performed for 3,500 hours at the test condition of 400 mA/cm2 and 700oC. The measured degradation rate is less than 1 %/1000hr, which indicates that the plasma-sprayed MS-SOFC cell made by INER reveals an inspired performance.
