Abstract
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 {degree sign}C under different current densities with open circuit voltage being 0.84 V over testing. 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 internal resistance in a porous stainless steel supported cell.
