Abstract
Provided is a method of making a composite ceramic material for a fuel cell. The composite ceramic material for the fuel cell forms a cored structure where perovskite ceramic particles having a small particle diameter surround lanthanum cobaltite particles having a large particle diameter. Lanthanum cobaltite is added as a starting material in a process of synthesizing the perovskite ceramic particles. The composite ceramic material for the fuel cell made according to this method improves an electric connection characteristic between a separation plate and a polar plate of the fuel cell, and is chemically and mechanically stable.
