▎ 摘  要

NOVELTY - Manufacturing carbon support involves obtaining an admixture comprising conductive carbon support and an organic material containing nitrogen (N), and heat-treating the admixture. USE - Manufacturing carbon support such as carbon black, acetylene black, carbon nanotubes, black lead, graphene, graphite nanofibers, fullerene, ketjen black, graphite, and ordered mesoporous carbon (claimed) for fuel cell catalyst. ADVANTAGE - The carbon support has excellent electrical conductivity, and high specific surface areas and acid/base stability, hence applied to electrochemical devices, and stability and corrosion resistance under an electrochemical atmosphere has been sought so as to maintain high efficiency and stable catalytic reaction in operating conditions of various fuel cells and it improves initial performance of fuel cells and secures long-term performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a catalyst for fuel cell, which is a metal supported on a carbon support.
