Title:
ELECTRODE CATALYST FOR FUEL CELL AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2002231257
Kind Code:
A
Abstract:
To provide an electrode catalyst for an anode of a fuel cell capable of exercising sufficient performance even when a supported amount of noble metal is reduced.
A method of manufacturing an electrode catalyst for a fuel cell comprises a process for producing ruthenium colloid particles by adding a reducing agent to a ruthenium salt solution, a process for bubbling hydrogen in a dispersed liquid in which the ruthenium colloid particles are dispersed, for allowing hydrogen to be adsorbed to the colloid particles, and a process for adding a solution of platinum salt to the dispersed liquid to produce ruthenium-platinum binary colloid particles containing ruthenium as its nucleus, and platinum on its surface.
