Discovery and characterization of novel oxide anodes for solid oxide fuel cells

The search for alternative anode materials for solid oxide fuel cells (SOFCs) has been reviewed in the light of structure, stability, conductivity, chemical and thermal compatibility with electrolyte YSZ. In this review, we have presented the advantages and disadvantages of the traditional Ni-YSZ anode for SOFCs. The development of alternative anode for SOFCs with fluorite, rutile, tungsten bronze, pyrochlore, perovskite and spinel structures has been reviewed and discussed in detail. Among the reported materials systems, materials with perovskite structure are promising particularly where two ions with complimentary function are present on the B-site at high concentration. We have recently found a good redox stable anode (La(0.75)Sr(0.25))(1-x)Cr(0.5)Mn(0.5)O(3) (0
