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： The method for coating a separator for a fuel cell according to one form of the present disclosure includes the steps of: vaporizing a metal nitride precursor to obtain a precursor gas; introducing a metal nitride coating layer-forming gas containing the precursor gas and a reactive gas to a reaction chamber; applying a voltage to the reaction chamber so that the precursor gas and reactive gas may be converted into a plasma state, thereby forming a metal nitride coating layer on a substrate; introducing a carbon layer-forming gas containing a carbonaceous gas to the reaction chamber; and applying a voltage to the reaction chamber so that the carbonaceous gas may be converted into a plasma state, thereby forming a carbon coating layer on the metal nitride coating layer.

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.
