Invention Description: [Technical Field of the Invention] The present invention relates to a method for transferring a nano-network-like platinum-based catalyst, and more particularly to a nano-synthesis synthesized on a treated substrate. A method in which a reticular platinum-based catalyst is transferred to a proton exchange membrane carrier. [Prior Art] In general, nanocatalysts currently used in direct Methanol Fuel Cell (DMFC) and Proton Exchange Membrane Fuel Cell (PEMFC) electrodes are applied approximately. There are three kinds: (1) directly coated on the proton exchange membrane, (2) first coated on a separable substrate and then transferred onto the proton exchange membrane, and (3) first coated on the electrode substrate. Direct hot pressing onto the proton exchange membrane. Among them, the amount of catalyst used in the previous two methods is relatively low. A typical example of a fuel cell catalyst electrode and a fuel cell having the catalyst electrode and a method for producing the above-described articles are disclosed in the Chinese Patent Publication No. 1222237, which is a catalyst for a fuel cell. The electrode includes: a substrate; and a catalyst layer formed adjacent to the substrate, comprising catalyst carrier carbon particles and a solid polymer electrolyte; wherein at least one of the substrate and the catalyst layer contains at least one Defoamer. For example, the fuel cell battery, the electrode for a fuel cell, and the method for producing the above article are disclosed in the Japanese Patent Publication No. 1250686, which is an electrode for a fuel cell. a collector on the surface of one side of the matrix; a catalyst layer on the surface of one side; characterized by: a mass, which is joined together. Recently, the research team has developed a nano-networked platinum-based catalyst composed of platinum and other responsible metals (the method is detailed in the implementation of Pt, Pt_Ru, etc.
