Solid Oxide Fuel Cell essentially works by merging of hydrogen rich gas and oxygen to create water and carbon dioxide, and obtaining electric current with this chemical reaction. Gases and liquids called “fuel” that contain hydrogen in its composition are used in SOFC as hydrogen source. Diesel, natural gas or alcohols can be given as examples. Air is used for oxygen source. Fuel and air react through a membrane to create water, carbon dioxide and electric energy. In this context, critical technology related to SOFC is the membrane. There are channels graved in metal to circulate hydrogen rich gas and air around the membrane. Metal with these channels allow collection of the created current since it also touches the membrane. This structure is called cell. A stack is obtained by piling these cells to reach the required energy amount.
