PROBLEM TO BE SOLVED: To provide: a catalyst ink for forming a fuel battery catalyst layer (electrode catalyst layer 52), which stays in a well dispersed state with stability even in the case of using platinum-supporting carbon particles low in dispersibility; and a method for manufacturing such a catalyst ink.SOLUTION: A method for manufacturing a catalyst ink for forming a fuel battery catalyst layer (an electrode catalyst layer 52) comprises: the step of mixing platinum-supporting carbon particles, a polymer electrolyte, and a mix solvent together while applying a strong impact of 300 G or larger by means of a bead mill.SELECTED DRAWING: Figure 1 |
