The Effect of Particle Size on the Performance of LSFC Perovskite Anode of Proton Conducting Solid Oxide Fuel Cell (PC-SOFC)

A promising and stable perovskite structure anode material La 0.3 Sr 0.7 Fe 0.7 Cr 0.3 O 3-x (LSFC) prepared by a glycine nitrate process was applied as the anode catalyst of a proton conducting solid oxide fuel cell (PC-SOFC). The particle size of the anode material could be controlled by varying the calcination temperatures. The influence of particle sizes on electrochemical performances had been studied. It was shown that the higher calcination temperature resulted in larger LSFC particles, which decreased the PC-SOFC performance significantly.
