Low Temperature Fabrication of Cathode-Supported Tubular Solid Oxide Fuel Cell by Co-Fire Process
摘要
Abstract
Strontium doped lanthanum manganite-yttria doped zirconia ( LSM-YSZ) tubular cathode support was prepared via an extrusion method. Cathode functional layer, electrolyte and anode thin films were sequentially deposited onto the cathode support with dip-coating technique, by co-sintering of which at low temperature, a cathode-supported tubular solid oxide fuel cell (SOFC) was fabricated. The micro-structure and electrical performance of the tubular SOFC were characterized by scanning electron microscopy and electrochemical workstation, respectively. The results showed that cathode functional layer, electrolyte and anode thin films are tightly sintered to the cathode support after co-sintering at 1220℃ for 8 h, and the YSZ electrolyte film is dense enough with thickness of about 15 /nm . The open circuit voltages of the single cell tested from 700℃ to 800℃ are all above 1. 0 V with humidified H2 as fuel and air as oxi-dant, which are close to the theoretical value, indicated that the electrolyte film has enough tightness. However, the cell demonstrated poor electrical performance, which maybe caused by the low conductivity and porosity of the cathode support. The cathode supported tubular SOFC was successfully fabricated by dip-coating method and subsequent co-sintering at low temperature, which is beneficial to low cost manufacturing of SOFC.关键词
