MANUFACTURING METHOD OF CATALYST FOR MEMBRANE-ELECTRODE ASSEMBLY

Abstract: provided is a method of producing a catalyst for a membrane-electrode assembly, the method including: preparing a precursor solution including a catalyst metal; preparing a seed solution by maintaining the precursor solution at a temperature within a first temperature range, lower than room temperature; maintaining the seed solution at a temperature within a second temperature range, higher than the first temperature range; and heating the seed solution to a temperature within a third temperature range, higher than the second temperature range.
