Abstract
The power generation experiments were carried out using the anodes of Ni/GDC(Gd_2O_3-doped CeO_2) with BCY(BaCe_<0.8>Y_<0.2>O_<3-δ>), Ni/GDC with SCYb(SrCe_<0.95>Yb_<0.05>O_<3-δ>), Ni/YSZ(Y_2O_3-stabilized ZrO_2) with SCYb and Ni/YSZ with SZY(SrZr_<0.95>Y_<0.05>O_<3-δ>) to investigate the effects of proton-conducting ceramics on the characteristic of anodes. The Ni/GDC-BCY (GDC:BCY=90:10vol%) anode had higher performance than Ni/GDC-SCYb (GDC:SCYb=90:10vol%) and Ni/YSZ-SZY(YSZ:SZY=70:30wt%). It seemed to be dependent on that BCY shows the highest conductivity of the three. However, Ni/YSZ-SZY had higher performance relatively. Although the SZY had lower proton conductivity, it seemed to have the contribution to the anodic reaction.
