中文摘要	In this study, a simple and cost-effective dry-pressing method has been used to fabricate a symmetrical solid oxide fuel cell (SOFC) where the dense yttria-stabilized zirconia (YSZ) electrolyte film is sandwiched between two symmetrical porous YSZ layers in which La(0.75)Sr(0.25)Cr(0.5)Mn(0.5)O(3-delta) (LSCM) based anode and cathode are incorporated using wet impregnation techniques. The maximum power densities (P(max)) of a single cell with 32 wt.% LSCM impregnated YSZ anode and cathode reach 333 and 265 mW cm(-2) at 900 degrees C in dry H(2) and CH(4), respectively. The cell performance is further improved with additional impregnation of a small amount of Sm-doped CeO(2) (SDC) or Ni. When 6 wt.% Ni as catalyst is added to both the anode and cathode. P(max) values of 559 and 547 mW cm(-2) can be achieved, which are better than with SDC. The effect of Ni on the cathode performance is also investigated by impedance spectra analysis.
