摘要： PURPOSE: Provided is a porous nanocarbon spherical support, which has improved conductivity and high surface area by heat treatment and is useful in manufacturing an electrode catalyst for a direct methanol fuel cell by dispersing Pt/Ru alloy nanoparticles. CONSTITUTION: The porous nanocarbon spherical support is manufactured by the method comprising the steps of: providing porous nanocarbon spherical particles by using a conventional method; heat treating the particles at high temperature under argon atmosphere; dispersing the heat treated particles in distilled water; carrying out ultrasonic treatment and centrifugal separation; and drying the resultant particles at 100 deg.C under vacuum. The electrode catalyst for a direct methanol fuel cell is obtained by adsorbing platinum(H2PtCl6) and ruthenium(RuCl3) ions on the above heat-treated porous nanocarbon spherical support and then reducing the ions with a reducing agent(NaBH4) at room temperature.
