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]
