Y and Nb-doped SrTiO3 as a mixed conducting anode for solid oxide fuel cells |
| 摘要 |
The invention disclosed relates to novel materials of the general formula (Sr1-1.5xM1x)1-y/2Ti1-yM2yO3 [I] wherein M1 is a first trivalent dopant metal atom replacing some of the strontium atoms on a strontium sub-lattice, x is a mole percent of said dopant atoms M1 on the strontium sublattice and 0<x<=0.04, and M2 is a second pentavalent dopant metal atom replacing some titanium atoms on a titanium sublattice, y is a mole percent of said dopant atoms M2 on the titanium sublattice and 0<y<=0.2. Also disclosed is a novel reduced form of the compounds of formula I, ie. compounds of formula (Sr1-1.5xM1x)1-y/2Ti1-yM2yO3-delta II. The variability in oxygen content between the oxidized and reduced forms of these compounds corresponds to 0<delta<=0.7. These novel compounds maintained a stable single phase at both high and low oxygen partial pressures. Also disclosed is a solid oxide fuel cell including an anode made of the novel compounds of formula I.
