Development of Ammonia-Fueled SOFC

Abstract

Ammonia has been studied as an energy carrier because of carbon-free and high hydrogen capacity. We have investigated performance of ammonia-fueled SOFC (Solid Oxide Fuel Cell) to study the possibility of ammonia as an energy carrier. In SOFC generation system, stack, which is made by cells, sealing glass and other materials, are main parts. These parts need ammonia resistance at 700-800 degree. So we developed sealing glass which has an ammonia resistance at 700-800 degree and fabricated 200W class stack. Ammonia was directly supplied to the anode chamber. The performance of ammonia-fueled SOFC was same as well as that of hydrogen-fueled SOFC.
