Title:
REDUCTION-OXIDATION-TOLERANT ELECTRODES FOR SOLID OXIDE FUEL CELLS
Document Type and Number:
WIPO Patent Application WO/2010/080507
Kind Code:
A3
Abstract:
An anode component of a solid oxide fuel cell is formed by combining a relatively coarse yttria-stabilized-zirconium (YSZ) powder, that is substantially composed of elongated particles, with a relatively fine NiO/YSZ or NiO powder of reduced particle size, whereby, upon sintering the combined powders, the coarse YSZ powder forms a microstructural cage of open porosity wherein the fine powder is distributed through the open porosity of the cage. A method of forming a cathode component includes combining a coarse YSZ powder, that is substantially composed of elongated particles, with a fine lanthanum strontium manganite powder of reduced particle size, whereby, upon sintering the combined powders, the coarse YSZ powder forms a microstructural cage of open porosity, wherein the fine powder is distributed through the open porosity of the cage.
