METHOD OF MANUFACTURING CATALYST COMPOSITE FOR FUEL CELL AND CATALYST COMPOSITE MANUFACTURED USING SAME

Resumen de: US20260360766A1

A method is provided for making a fuel-cell catalyst composite by using a two-layer solvent. A metal catalyst precursor is dissolved in a first solvent and a second solvent that does not dissolve the precursor is added to form two layers. The two-layer solution is used to impregnate a porous support, the support is dried, and the precursor is reduced so that a metal catalyst is supported on the support. By adjusting the volume ratio of the first and second solvents, the average particle size and dispersion of the supported metal can be controlled. In preferred cases, the support includes mesopores with a mesopore utilization ratio of 50% to 80%, and at least 30.5% of the total supported metal resides inside the pores. The approach improves poisoning resistance and durability of fuel cells.
