Electrochemical performance of barium strontium cobalt ferrite - samarium doped ceria - argentum for low temperature solid oxide fuel cell

A low operating temperature is one of the concerns in commercialising solid oxide fuel cells (SOFCs) as a portable power source. The aim of this research is to develop a new cathode material, barium strontium cobalt ferrite–samarium doped ceria (BSCF-SDC) added with argentum (Ag) for low-temperat...
