Abstract

Metal-supported solid oxide fuel cells (SOFCs) have the advantage of the thermal shock resistance and higher mechanical strength compared with anode-supported SOFCs. In this study, Ni-Fe metal was used as supporting metal. The supporting metal was initially prepared in oxide form of NiO-Fe2O3, and co-sintered with Gd-doped ceria electrolyte at 1350ºC for 3h in air and later reduced to Ni-Fe metal. Two different cells were prepared and compared to see the effect of the thickness of the electrolyte and the role of the electrode on the performance of the cell.
