PROBLEM TO BE SOLVED: To obtain ink for catalyst, the ink obtaining catalyst carrying particles on the surface of which ionomer is bonded firmly, while preparing at low cost by a simple method.SOLUTION: The ink for catalyst for forming a catalyst layer in a membrane-electrode assembly equipped with a solid polymer electrolyte membrane is obtained by mixing, stirring and dispersing catalyst carrying particles 1, ionomer 3, a solvent, and an amphiphillic saccharide. Trehalose is specifically suitable as an amphiphillic saccharide. |
