Fabrication and Chacterization of Planar Solid Oxide Fuel Cell

평판형 고체산화물 연료전지 제조 및 특성 연구

Solid oxide fuel cell(SOFC) is an electrochemical energy device which converts the free energy of fuel gas directly to electric energy. SOFC has several diratinct advantages over other types of fuel cells: no use of noble metals, no requirement of a reformer, no problem of liquid electrolyte management, and no problem of corrosion by liquid electrolyte. In this study, we have investigated the cell components and the single cell of the planar SOFC fabricated by composite plate process, in which green films of electrolyte, anode and cathode were co-fired. The planar SOFCs were tested and the cell performance characteristics wag evaluated by using electrochemical methods.
