▎ 摘  要

NOVELTY - Anode catalyst of polymer electrolyte fuel cell comprises: titanium nitride as catalytically active component, which is supported on a catalyst support including carbon nanotubes and graphene. USE - The catalyst is useful in domestic power supply and transportation including car. ADVANTAGE - The catalyst can be produced in simple, easy and cost effective manner; is stable; and exhibits high activity and reduction properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the anode catalyst of polymer electrolyte fuel cell, comprising: preparing a mixed solution containing the catalyst support by mixing carbon nanotubes and graphene oxide in a solvent; preparing a mixed solution containing catalytically active component by mixing titanium salt in a solvent; mixing the mixed solution including the catalyst support and the mixed solution including the catalytically active component, and adding a nitrogen source to combine titanium-nitrogen complex with the catalyst support and to prepare a solution; and obtaining carbon nanotube-graphene composite supported titanium nitride by nitrogen sintering at 750-800 degrees C.
