The performance of a single-chamber solid oxide fuel cell was
studied using a ceria-based solid electrolyte at temperatures below 773 kelvin. Electromotive forces of ~900 millivolts were generated from
the cell in a flowing mixture of ethane or propane and air, where the
solid electrolyte functioned as a purely ionic conductor. The
electrode-reaction resistance was negligibly small in the total
internal resistances of the cell. The resulting peak power density
reached 403 and 101 milliwatts per square centimeter at 773 and
623 kelvin, respectively.
