Method of preparing catalyst for fuel cell

摘要

A method of preparing a fuel cell catalyst includes preparing a catalyst precursor solution by mixing a catalyst precursor and a solvent, and subjecting the catalyst precursor solution to radiation of electron beams having energy of less than or equal to 1 MeV. A method of preparing the fuel cell catalyst uses electron beams having low energy so that it can provide a desirable catalyst uniformly in a simple and economical process, as well as releasing few X-rays so that the catalyst can be mass produced.
