Discovering exceptional oxide ion conductivity at lower temperatures - EurekAlert
<p>Oxide ion conductors used in solid-state fuel cells often fail to reach full potential when operating at temperatures below 500 <sup>o</sup>C, but researchers from Tokyo Tech have recently found a solution to this problem. They demonstrated high conductivity and stability in bismuth-containing Sillén oxyhalides with triple fluorite-like layers (e.g. 10 mS/cm at 431<sup> o</sup>C; 204 times higher conductivity than that of conventional conductors at 310<sup> o</sup>C).</p>
