FUEL ELECTRODE WHICH ALSO SERVES AS SUPPORTING BODY OF SOLID OXIDE FUEL CELL, AND FUEL ELECTRODE-SUPPORTED SOLID OXIDE FUEL CELL

摘要

The present invention provides a fuel electrode doubling as a support of a solid oxide fuel cell that hardly deteriorates conductivity and strength thereof through repetitive exposure to reducing atmosphere/oxidizing atmosphere. The fuel electrode doubling as the support of the solid oxide fuel cell according to the present invention includes: a porous structure formed of first oxide particles having a 10% cumulative particle diameter between 5 µm and 12 µm and a 90% cumulative particle diameter between 84 µm and 101 µm; and electrode particles having an electrode catalytic activity that cover a surface in a gap of the porous structure and have a surface covered with second oxide particles by 10% to 70%.
