The invention discloses continuous equipment for producing a fuel cell platinum-carbon catalyst and a preparation method of the continuous equipment, the continuous equipment comprises a reaction kettle group and cleaning and drying equipment, and the preparation method comprises the steps of raw material mixing, pre-heating, heating and first reaction, cooling and second reaction, cleaning and drying. The continuous production of the fuel cell platinum-carbon catalyst is realized by connecting a plurality of reaction kettles in series, 10-200g of the platinum-carbon catalyst with the platinum loading capacity of 20-70% and the average particle size of 2-5nm is produced in each batch, high efficiency, energy conservation and no gas emission are realized, a mixed solution sequentially passes through each reaction kettle in the production process, each step can be synchronously carried out, and the production cost is reduced. Partial damaged parts of the reaction kettles can be directly maintained and replaced,
