摘要
The electrochemical performances and the morphologies of Ni/SDC anodes fabricated by EPD technique were investigated for direct oxidation of dry CH4 in solid oxide fuel cells (SOFCs). Ni/SDC(EPD) anode with both 20 wt% of Ni content and 20 mu m of thickness exhibited the lowest overpotential and the highest maximum power density for dry CH4-air SOFC at 973 K. The power density of the cell with Ni/SDC(EPD) anode was higher than that with Ni/SDC fabricated by a conventional slurry coating method. It was found that Ni/SDC(EPD) anode having dense structure suppressed carbon deposition and exhibited a stable cell operation in SOFC using dry CH4. (C) 2008 Elsevier B.V. All rights reserved.
