Abstract
Metal supported solid oxide fuel cell (SOFC) replaces usual ceramic support with metal for enhancing mechanical strength. Metal supported SOFC has high mechanical strength, better resistance to vibrations and impact than conventional SOFC. In this study, 3-layer metal supported SOFC short stack was designed and developed for auxiliary power unit (APU) application. For the development of metal supported SOFC stack, metal supported SOFC was fabricated by sinter joining process. Electrochemical performance of the short stack was evaluated in 800°C. The short stack showed 3.0V of open circuit voltage (OCV) and 23.1 W of maximum power. The short stack operated for 120 hours in galvanostatic mode with 2.16 A of discharge current and 2.0 V of initial voltage. After 120 hours, voltage of the short stack was 1.81 V and its degradation rate was 9.5 % per 120 hours.
