Description of the invention: [Technical field to which the invention pertains] The present invention relates to a catalyst containing a catalyst, and more particularly to a solution of a platinum catalyst nanoparticle having a start-to-start bond (Pt_; pt bond) , its method of manufacture, and its use in fuel cell electrodes and/or fuel cell membrane electrode sets (Membrane Electrode Assembly). [Prior Art] 'Nano-grade metal particles, hereinafter referred to as nano-particles, have attracted the attention of many researchers because of their commercial potential in the fields of catalysts, adsorbents and sensory devices. Because the dissolution method can easily change the shape and size of nano particles by controlling the chemical parameters of the solution, the sol_gelmeth〇d method has become the most important way to prepare nano particles in the past decade. A method for reducing metal salts by a decyl alcohol solution in the presence of a stabilizer having a space barrier has been developed by et al. They studied the mechanism of nanoparticle formation in the Rh-(polyvinyl alcohol)-methanol-water system, and also studied the formation mechanism of nanoparticles in H2PtCl6-(p〇lyvinyl pyrrolidone; PVP)-methanol_water. Teranishi Τ· et al. studied the preparation of platinum colloids by the protective agents s〇dium polyacrylate (ΜΑ) and PVP, reducing agent hydrogen and sterol to reduce hexachloroplatinic acid. Chen and Shi hi by reducing agent ethanol, protective agent poly(Mnylfo^mide), p〇ly φ and ? 0匕(#七〇1^加如^6) reduces ubi-(:162- to prepare nanoparticles. However, various conventional methods described above use high molecular weight stabilizers, which are prone to poisoning or obscuration. The surface activity of the nanoparticles, therefore, the conventional method must include a removal step to remove the stabilizer, so that the surface of the nanoparticles is poisoned or other side reactions occur in subsequent processes. However, the removal often uses high-burning. In the way of pyrolysis or extraction, these operations often cause nanoparticle 4^4. In view of this, there is still a need to develop a new process to produce a fine dispersion with high dispersion, particle size distribution and stable aggregation. Nylon particles, and meet the requirements of simple method, low cost, simplified removal step or directly omit the removal step, which is also quite important in the industry 6 1304357 factory [invention content; ^ ^ ^ ^ ^ ^ ^ ^ v , # In the above-mentioned invention background, in order to meet the requirements of the industry, the cup is a record of death, the construction, the method of manufacturing the same, and the application thereof in the fuel cell.
