摘要：

Fabrication and characterization of tubular SOFCs under sub-millimeter (0.8 mm), bundles and stacks for low temperature operation were shown. The materials used in this study were Gd doped CeO2 (GDQ for electrolyte, NiO-GDC for anode and (La, Sr)(Co, Fe)03 (LSCF)-GDC for cathode, respectively, and LSCF for supports of the tubular cells for bundle fabrication. After applying a sealing layer and current collector for each bundle of five micro tubular SOFCs, each bundle was stacked vertically, to build a four-storey cube-type stack with volume of about 0.8 cm(3). The performance of the stack was shown to be 3.6V OCV and 2W maximum output power under 500 degrees C operating temperature. Preliminary quick start-up test was also conducted at the condition of 3 min start-up time from 150 to 400,C for 5 times, and the results showed no degradation of the performance during the test.
