ELECTRODE MATERIAL FOR FUEL CELL AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a manufacturing method of an electrode material capable of yielding in a paste form, which is easy to mold, by precipitating, separating and calcining in a co-precipitation method by using a precursor solution of nickel and iron. The manufacturing method of an electrode material comprises (1) a mixing step of mixing a nickel precursor solution and an iron precursor solution to obtain a precursor mixture; (2) a precipitation step of adding a precipitating agent to the precursor mixture obtained at the mixing step to precipitate as precipitate; (3) a drying step of drying the precipitate obtained at the precipitation step; (4) a calcination step of calcining the dried precipitate obtained at the drying step; and (5) a pulverization step of pulverizing the calcined precipitate obtained at the calcination step with a binder to obtain an electrode material mixture.
