Title:
FUEL CELL CATALYST AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/191396
Kind Code:
A1
Abstract:
The present invention relates to a fuel cell catalyst preparation method and a fuel cell catalyst, the method comprising the steps of: (a) permeating a metal catalyst precursor or a metal catalyst seed into pores in a porous support; (b) producing metal catalyst particles by reducing the metal catalyst precursor or the metal catalyst seed; (c) removing metal catalyst particles which are outside of the pores of the support or which exhibit a weak binding force; and (d) by reducing and growing the metal catalyst particles by adding an additional metal catalyst precursor and a reducing agent, obtaining post-growth metal catalyst particles which are more stably supported.
