A method for manufacturing an alloy catalyst for a fuel cell is disclosed. The method for manufacturing an alloy catalyst for a fuel cell may include predetermined processes and reaction conditions, such that iridium is alloyed to platinum contained in a cathode carbon support catalyst. Accordingly, time for stabilizing charge on the carbon surface may be reduced and a metal particle size may be controlled, thereby manufacturing high quality products having uniform metal particle distribution and improved durability. In addition, corrosion of a cathode carbon support catalyst in a harsh condition such as vehicle driving may be prevented.

Method for manufacturing alloy catalyst for fuel cell

Titanium suboxide (TiO) nanoparticles useful as a support for a catalyst electrode of a fuel cell, and a method for synthesizing the titanium suboxide (TiO) nanoparticles by using TiO, a Co catalyst and hydrogen gas at a low temperature ranging from 600 to 900&#xb0; C. are described Since the titanium suboxide nanoparticles show high corrosion resistance to acid and durability and have excellent thermal and electric conductivities, a catalyst electrode manufactured by using the same as a support exhibits improved catalytic activity and oxidation reduction (redox) properties.
