Porous stainless steel supported solid oxide fuel cells having nickel-ceria cermet anode, ceria electrolyte and lanthanum strontium iron cobalt perovskite cathode were fabricated by using inexpensive technologies of spraying, pressing and firing. A ceria cell fabricated on a porous support was found to show long-term stability over 1000 hours at 600\ub0C under different current densities with open circuit voltage being 0.84 V. It was shown that gas permeability in porous support had a great influence on fuel cell characteristics, and that cathode polarization accounted for half of the internal resistance in a porous stainless steel supported cell.Peer reviewed: YesNRC publication: Ye
