▎ 摘　　要

NOVELTY - A stable ceramic-based load fuel cell catalyst preparing method involves modifying a graphene oxide microchip with a surfactant, mixing uniformly with a zirconium diboride powder under phenolic resin, ball milling under high pressure, and heat treating under a high temperature inert atmosphere to form a zirconium diboride-graphene oxide composite material. The zirconium diboride-graphene oxide composite material is arranged in deionized water to the suspension, added with a chloroplatinic acid hexahydrate and a reducing agent, adjusted pH to alkaline with ammonia water, heated, refluxed and allowed to stand in an incubator to form a zirconium diboride supported platinum graphene suspension. The suspension is filtered, washed and dried to obtain the finished product, where the weight ratio of the graphene oxide microchip, the zirconium diboride powder, the phenolic resin, the chloroplatinic acid hexahydrate, and the reducing agent is 2-7:15-25:15-20:2-5:2-7. USE - Method for preparing stable ceramic-based supported fuel cell catalyst. ADVANTAGE - The method enables preparing stable ceramic-based supported fuel cell catalyst with high electron mobility and better tolerance of impurity gas and in simple manner, in simple and cost effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a stable ceramic-based load fuel cell catalyst prepared by the method.
