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： The present disclosure relates to a method of manufacturing an electrolyte membrane for fuel cells capable of effectively removing hydrogen and/or air crossing over. Specifically, the method includes coating a slurry including at least an ionomer on a substrate to manufacture an ion transfer layer, manufacturing a laminate including the substrate and the ion transfer layer, and providing a pair of laminates to form an electrolyte membrane, wherein the ion transfer layer has a catalyst region formed at one side thereof based on a width-direction center line thereof, the catalyst region including a catalyst.
