Abstract
A SOFC half cell of the present invention includes: an anode functional layer (11) containing yttria-stabilized zirconia and a conductive component containing a metal oxide that changes to an electrically conductive metal in a reducing atmosphere; and a first electrolyte layer (21) containing yttria-stabilized zirconia as a main component and formed on one principal surface of the anode functional layer (11). The yttria-stabilized zirconia in the anode functional layer (11) has an yttria content of more than 9.00 mol % and 11 mol % or less, and the yttria-stabilized zirconia in the first electrolyte layer (21) has an yttria content of more than 9.00 mol % and 11 mol % or less. This half cell allows the SOFC to exhibit high power generation performance.
