La0.7Sr0.15Ca0.15Co1-yFeyO3-δ(LSCCF)powders with 0.2y0.5 for the applications as the cathode materials in intermediate temperature solid oxide fuel cell(ITSOFC) were synthesized by glycine-nitrates-process(GNP) using metal-nitrates and glycine as the raw materials.
Therefore, the LSCF has become the recent focus of ITSOFC cathode materials research since it can reduce the operation temperature of SOFC using LSCF as cathode materials [1-5].
For researched the performances and synthesis method of cathode materials deeply, La0.7Sr0.15Ca0.15Co1-yFeyO3- cathode materials were prepared by glycine-nitrates-process (GNP), and the influences of B site doped on performances were researched in this paper.

Acceptor-doped lanthanum manganite materials have a potential in application of electrochemical devices [7].
In addition, this general class of materials, displays interesting and potentially useful catalytic and magnetoresistant properties.
Due to the high conductivity of manganites-based perovskite, there are only a few studies on the dielectric properties materials [10].
