METHODS OF MAKING MESOPOROUS METAL OXIDE COMPOSITIONS AND SOLID OXIDE FUEL CELLS

摘要

The invention discloses methods of producing thermally stable mesoporous transition metal oxide compositions by aqueous co-assembly of glycometallate s and metal complexes with a surfactant template, without the necessity of the use of stabilizers. Mesoporous (nickel/platinum)-yttria-zirconia materials a re also disclosed for use as electrode materials in solid oxide fuel cells. The se materials display the highest surface area of any form of (metal)-yttria- stabilized-zirconia, thereby providing significant improvement in the efficiency of solid oxide fuel cells.
