Abstract: Disclosed are a membrane-electrode assembly (MEA) and a method of manufacturing the same. The MEA include an electrolyte membrane and a pair of electrodes, the electrodes being disposed on both surfaces of the electrolyte membrane, respectively. At least one of the electrolyte membranes and electrodes includes an ion-conducting polymer having a proton-conducting functional group, and a compound represented by Chemical Formula 1 is bonded to each of all or some of the proton-conducting functional groups: MAx??[Chemical Formula 1] wherein M is an element belonging to the lanthanum group, A is a hydrophilic functional group, and X is a numerical value for balance of charges between A and M. Since the MEA includes an ion-conducting polymer having good chemical durability and proton conductivity, the MEA is durable and has high proton conductivity.
