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.

摘要： Disclosed is a method of manufacturing a membrane-electrode assembly for fuel cells. The method includes (a) admixing a metal catalyst, an ionomer and a first dispersion solvent to prepare a first admixture, (b) heat treating the first admixture prepared in (a) to form an ionomer-fixed metal catalyst, and (c) immersing the ionomer-fixed metal catalyst formed in (b) in a solvent, wherein the solvent in (c) may include one or more selected from the group consisting of ethanol, propanol, and isopropyl alcohol. The membrane-electrode assembly for fuel cells manufactured by the method may have substantially improved durability.

摘要： Disclosed are a method of manufacturing a membrane electrode assembly for a fuel cell and a membrane electrode assembly for a fuel cell manufactured using the same. The planar membrane electrode assembly for a fuel cell may include an ionomer membrane formed on both side surfaces of an electrode and between the electrode and an electrolyte membrane, thereby increasing interfacial bonding force between the electrode and the electrolyte membrane and improving the durability of a cell. In addition, the membrane electrode assembly may include planar or smooth surfaces such that formation of voids or surface steps between the electrode and a sub-gasket may be prevented, thereby improving airtightness and preventing deterioration attributable to concentration of pressure.
