Single chamber solid oxide fuel cells generate electricity using hydrogen and hydrocarbon fuel mixed with oxygen at intermediate temperatures (400-800°C) without using seals to separate the gases. A single-chamber solid oxide fuel cell was fabricated with a porous samaria doped ceria (SOC) electrolyte, nickel oxide anode, and a lanthanum strontium cobalt iron oxide (LSCF) cathode. Instead of separately sintering the different components at different temperatures, the electrolyte and electrodes were co-sintered at 1100°C. The porous SOC electrolyte approached 84% theoretical density when sintered at 1100° C. The fuel cell had a maximum open circuit voltage of .65 V at 550°C. The conductivity of the porous SOC electrolyte was greater than dense yttria-stabilized zirconia (YSZ) electrolytes but less than that of dense SOC electrolytes. Further studies will be conducted to determine the durability and to refine the heating schedule for simultaneous sintering of these fuel cells.
