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.

A method of evaluating a movement tendency of ions in an electrolyte membrane includes counting inter-movement ions, counting intra-movement ions and calculating the ratio of the intra-movement ions and inter-movement of ions. The movement tendency of ions is predicted based on the ratio. In the case of evaluating a movement tendency of ions using the method, since the structure of the electrolyte membrane in which the ratios of intra-movement and inter-movement are maximized is predicted through measurement of the ratios of the intra-movement and inter-movement of ions, ohmic resistance that may occur in a membrane-electrode assembly (MEA) may be reduced. The electrolyte membrane having the optimal structure predicted by the method can be applied to a fuel cell to increase its performance.
