Abstract:Solid oxide fuel cell (SOFC) is a promising technology for the hydrogen economy and clean energy production. However, the classical SOFC employing fluorite-type electrolytes such as yttrium-stabilized zirconia (YSZ) and Gd3+/Sm3+-doped CeO2 (GDC/SDC) faces significant technical challenges due to the required high operational temperature. Here, a groundbreaking result on alumina in fluorite structure deviated from the amorphous phase with high oxygen vacancy concentration is reported. Unlike lower valency catio… Show more
