Fabrication and characterization of YSZ/ScSZ bilayer electrolyte via Cold- Isostatic Pressing (CIP) method for intermediate temperature-solid oxide fuel cell (IT-SOFC) application
Solid oxide fuel cell (SOFC) technology has advanced significantly in the recent years, and now is an interest of many renewable energy-related industries to invest. However, the main issue of SOFC is the high operating temperature that negatively influence its performance. To reduce the temperature...
