摘要： Disclosed is a method of preparing a catalyst having a conductive oxide protective layer. The method may include providing (e.g., supplying) a carbon support having a metal catalyst supported thereon to a fluidized bed reactor, and forming a conductive oxide protective layer using atomic layer deposition (ALD). Particularly, the atomic layer deposition may include supplying a conductive oxide precursor to the fluidized bed reactor, conducting a first purging by supplying an inert gas to the fluidized bed reactor, converting the conductive oxide precursor to conductive oxide by supplying a reactive gas to the fluidized bed reactor, and conducting a second purging by supplying an inert gas to the fluidized bed reactor.

摘要： Disclosed is a method for preparing a metal catalyst composite. The method includes pre-treating a carbon support in a reactor, and depositing a metal precursor on the pre-treated carbon support. The pre-treating the carbon support may include exposing the carbon support to a nucleating agent, for example, titanium tetrachloride (TiCl4), silicon tetrachloride (SiCl4) and carbon tetrachloride (CCl4).

摘要： Disclosed are a catalyst complex and a method of manufacturing the same. The catalyst complex may be manufactured by uniformly depositing metal catalyst particles on pretreated support particles through an atomic layer deposition process using a fluidized-bed reactor, which may be then uniformly dispersed throughout the ionomer solution. As such, manufacturing costs may be reduced due to the use of a small amount of metal catalyst particles and the durability of an electrolyte membrane and OCV may increase. Further disclosed are a method of manufacturing the catalyst complex, an electrolyte membrane including the catalyst complex, and a method of manufacturing the electrolyte membrane.
