Abstract

Excellent performance has been achieved at 400-600 degrees C for fuel cells based on doped-ceria-carbonate composite electrolytes: however, the fuel cell stability remains a big challenge for practical applications. In this communication, we report the stable performance of a fuel cell based on doped-ceria-carbonate composite electrolyte and Sm0.5Sr0.5Fe0.8Cu0.2O3-delta cathode. At 550 degrees C, current output of about 400 mAcm(-2) was continually generated during the non-stop 100 hour measurement under constant voltage of 0.7 V although further investigation is needed for longer term stability. This type of intermediate temperature fuel cell is promising for real applications.
