Abstract:
The present invention relates to a process for the preparation of electrochemical catalysts of the polymer electrolytes-based fuel cells. With the process of the present invention, high catalyst activity while uniformly supporting a large amount of metal particles on a surface of a support can be achieved. Also, the present invention provides a process for the preparation of electrochemical catalysts of the polymer electrolytes-based fuel cells capable of using a small amount of toxic solvent without an additional high-temperature hydrogen annealing.
