Solid Alkaline Fuel Cell Composed of Layered Perovskite-Type Oxide LaSr_3Fe_3O_(10)

摘要

In the present study, solid alkaline fuel cell composed of layered perovskite-type oxide LaSr_3Fe_3O_(10) was studied. LaSr_3Fe_3O_(10) showed OH~- conduction and activity for oxygen reduction reaction. We prepared LaSr_3Fe_3O_(10) with various bulk density by sintering at 900, 1100, 1200, 1400, and 1600°C. When the bulk density increased from 4.03 (sintered at 900°C) to 4.16 g cm~(-3) (sintered at 1100°C), the output power and open circuit voltage increased greatly. However, when the bulk was higher than 4.16 g cm~(-3), output power decreased with an increase in bulk density.
