Electrical properties of oxyapatite-type solid electrolyte and its application to solid oxide fuel cell

A. Mineshige M. Momai A. Matsumaru S. Yagi T. Yazawa

ECS Transactions 91(1) 1129-1138 2019年

Lanthanum silicate oxyapatite (LSO) attracts attention as an alternative electrolyte material for the intermediate-temperature solid oxide fuel cells (SOFCs). However, controlling factors of its conductivity and activation energy values have not b...
