The composite cathode La0.6Sr0.4Co0.2Fe0.8O3-?(LSCF) powder and Ce0.78Gd0.2Sr0.02O2-?(GDCSr) nanofiber are investigated for IT SOFC.A mixing method was used to fabricate nanofibers composite cathode by adding various wt.% of GDCSr nanofibers (20, 50, and 80wt.%) into LSCF powder using conventional heating....
