AbstractA tri-layer comprising a lanthanum strontium cobalt iron perovskite cathode, a doped ceria electrolyte and a nickel ceria cermet anode was fabricated on a porous stainless steel substrate by a series of processing steps involving wet powder spraying, lamination and sintering, and was tested with humidified 50 % hydrogen in argon supplied to anode and air supplied to cathode at intermediate temperatures of 650 and 600 °C. Open circuit voltage showed relatively lower values, below 0.75 V, however the cell was found to deliver higher current densities, over 1 A/cm2, and achieved a maximum power density of over 450 mW/cm2 at 650 °C. It was found that the cathode accounted for most of the polarization resistance and that the anode polarization was less influential to the ceria cell tested.
