Abstract |
Solid oxide fuel cells (SOFCs) are one of the most efficient energy conversion devices. The main demand in the current SOFC development is lowering operation temperature to the range of 600˚C - 800˚C. It has been shown that in this temperature range anode supported SOFC is a very promising design. The application of thin film techniques to the electrolyte processing allows decreasing electrolyte resistance and as a result improves fuel cell performance. A nickel cermet, which contains nickel (usually from 40 to 60 vol.%) and yttria stabilized zirconia or ceria, is typically used as an anode. However, nickel cermet during oxidation and reduction is subjected to intense volume change which may lead to destruction of thin film electrolyte or cermet structure.
