Abstract
Metal supported solid oxide fuel cells (SOFCs) are one of the most promising candidates for power plants as well as portable applications due to their good mechanical and thermal properties. In this study, the thin NiFe supported SOFC, which consisted of thin metal support (NiFe, similar to 70 mu m), anode functional layer (Ni-YSZ, similar to 30 mu m), electrolyte (YSZ, similar to 15 mu m), and cathode (LSCF, similar to 30 mu m), was fabricated through tape casting and co-firing method. The cell showed 1.05-1.1 V of open circuit voltage and 1.4 W cm(-2) of maximum power density at 800 degrees C with the ohmic resistance (Rohm) of 0.12 Omega cm(2) and the polarization resistance (R(p)) of 0.38 Omega cm(2). The high performance and the successful measurement of thin metal supported cell showed the possibility for mobile applications through the large area cell fabrications. (C) 2010 Elsevier Ltd.
