“…For PCFCs, the potential anode materials Ni-Ba(Ce,Y)O 3- (Ni-BCY) [5,6], NiBa(Zr,Y)O 3- (Ni-BZY) [7], Ba(Ce,Zr,Y,Yb)O 3- [8], Ni-SrCe 0.9 Yb 0.1 O 3-δ [9] Ca(Zr,Y)O 3- , Ni-Sr(Zr,Y)O 3- [10] and Ni-Ba(Ce,Zr,Y)O 3- [11][12][13][14] have been reported in the literature. Due to the instability of BCY in H 2 O and CO 2 containing atmospheres, cermet anodes of Ni-BCY may be unsuitable for practical operation in alternative carbonaceous fuels [4].…”
