Abstract

A novel composite cathode material for cathode-supported direct carbon fuel cells (DCFCs) was developed and characterized in terms of phase stability, sintering behavior, electrical conductivity, mechanical strengths and microstructures. It was found that the newly developed LSM/GDC composite provides sufficient level of mechanical strength, electrical conductivity and porosity after sintering at 1300 °C and does not form any undesirable secondary insulating phases. The sintering behavior study showed that GDC inhibits sintering of LSM and thermal expansion coefficient (TEC) is compatible with other cell components. The preliminary results showed that LSM/GDC composite is suitable for cathode support applications.
